Mount Everest, the most familiar peak to people. Mountaineers regard climbing Everest as a glory of self-conquest, while scientists call it the "Third Pole" of the world, which, like the North and South Poles, is an important geographical landmark in our Earth's home, attracting numerous scientists to explore its secrets.

00:00It's the best way to go to the line.
00:09I just don't know how to do it.
00:16How are you playing?
00:18How are you playing?
00:20They were in the 8100,
00:27and there was still a bit of a danger.
00:31If we don't want to go back,
00:35we definitely don't want to go back.
00:36You can see what's going on in the middle of the road?
00:43It's all dark.
00:45I can't see.
00:4660 years earlier, a Chinese team summited the world's highest mountain, Mount Chomolangma,
00:57for the first time.
01:0145 years earlier, a Chinese climbing team measured its height at 8,848.13 meters.
01:09Then, 15 years earlier, another Chinese team again measured the elevation of its summit
01:17and updated the number to 8,844.43 meters.
01:282020 is another year for elevation surveys, as well as an opportunity to pay homage to
01:34the achievements of earlier experts.
01:39This time, however, the team of mountaineers and scientists involved are facing a harsh
01:47challenge.
02:09The COVID-19 pandemic has hindered the 2020 team's preparations, leaving it with only
02:15one month to fulfill its task.
02:17That month is May, the best time for climbing Mount Chomolangma.
02:25The last supply station for the Chinese expedition, the Advance Camp, lies on Mount Chomolangma's
02:30north slope, at an altitude of about 6,500 meters.
02:36Although the stop's extreme conditions have earned it the nickname, the Devil's Camp, the mountaineers
02:42have no other choice.
02:43Pre-cooked food, boiled with melted snow, provides energy needed by the team members for the final
03:05days of their climb.
03:09Altitude reaction is depriving them of appetite, but they have to take in nutrition.
03:15As they climb higher, only cold snacks will be available.
03:22In the final stage of their ascent, the climbers will be dangerously exhausted.
03:40To keep their load as light as possible, they will only carry some nuts, cookies, and soft
03:45drinks to sustain them for at least three days.
03:49But I'm prepared for a lot of time, because we'll have to take a lot of time for a night.
04:03In 1960, the mountaineers Wang Fuzhou, Kun Bo, and Chu Yin Hua, who represented China,
04:10reached the summit of Mount Chomolangma for the first time, opening a route from the mountain's
04:15north side.
04:17This is the route being used by the 2020 expedition.
04:29The Northridge route is about 23.7 kilometers long.
04:33It starts from China's 5,200-meter base camp, and ascends along the Rongbuk glacier, with an
04:40overnight stay at the route's 5,800-meter transition camp.
04:46After passing the 6,500-meter advance camp, the team must tackle the North Cole ice wall.
04:54The top half somewhere in the northern Ivy League has been launched for a few months,
04:55in Europe.
04:56The question was, is the first one?
04:57The first one?
04:58The first one is from the door of the
05:12northern Ivy League, which is a meter need for the number ofкомils, and it's much more
05:15Zuzun's Zuzun's Mall.
05:16Avalanches are very dangerous for mountaineers.
05:31But the number one camp of the route's final ascent phase
05:34is built on the North Cole ice wall at 7,028 metres.
05:42With deep snow above, the real challenge
05:45starts here.
06:15This wind gap is between Mount Chomalangma's north side and Mount Changzi.
06:18Along this section, unpredictable air flow resulting from the terrain can suddenly build
06:22into a gale on sunny days.
06:24Mount Chomalangma must then use their experience to decide whether or not to continue their
06:31ascent.
06:32If they make it through the wind gap, climbers spend a night at number two camp at 7,790 metres
06:39before continuing on.
06:41The route's number three camp at 8,390 metres before continuing on.
06:48The route's number three camp at 8,300 metres is the final rest station before the summit.
06:55Totally exhausted at an extreme altitude, climbers do not spend long in the final camp.
07:02To arrive at the summit with enough time to descend, they get up for the last stretch at 2 a.m.
07:09At 2 a.m.
07:10At 8,300 metres at 8,300 metres at 8,300 metres is the final rest station before the summit.
07:19Totally exhausted at an extreme altitude, climbers do not spend long in the final camp.
07:26At 8,300 metres at 8,300 metres at 8,300 metres at 9,700 metres after obfusion.
07:55Despite the dangers, the experience of ascending via the North Ridge route, accumulated by their predecessors over 60 years, helps the Chinese team through the challenge.
08:13A sound climbing plan has been mapped out by them ahead of time.
08:25And in the end, in the end, we have chosen a better experience with a better experience and a better quality of the technology.
08:33In the end, it represents a better experience with all the players, all the players, and all the players.
08:47Unfavorable weather has suspended the first attempt at Peking.
08:51As time passes, the camp falls into silence.
08:57The weather forecast says the next period of good weather will last for four days.
09:05Now is no time for relaxation.
09:08The surveyors use the downtime to practice operating their equipment.
09:13First time we have to build the 6500 feet, we have no direction before we reach the level of 6800 feet.
09:18Since we've reached the border to the 6700 feet or 6800 feet, we have been able to get it.
09:24So we've been able to get the first chance to see your first chance.
09:26And in the end, we still have a bit of a bit of a nervous pressure.
09:30The mountaineering team will carry a surveyor's beacon, a gravimeter, a snow-depth radar,
09:57and a Beidou navigation satellite signal receiver to the peak.
10:03To guarantee successful measurements, the team's surveyors need to be experts in mountaineering
10:08and its mountaineers have to master equipment operation.
10:12Their measurements should be done neatly and fast in order to keep their stay on the summit
10:17short and reduce danger.
10:27The mountaineering team will be able to keep their stay on the mountaineering team.
10:34It's 3 o'clock, I'm here.
10:37I'm really tired.
10:40The old man was up to 5,300.
10:42He was pulled up to the top.
10:44You're still the top man who is the top man.
10:47It's 8,000 or 9,000.
10:49We don't have a lot of people.
10:51Ren Xiu Wu is 40 years old.
10:56He participated in the 2005 Mt. Chomolongma Elevation Survey.
11:01Today, he will climb to the route's 3-7 measuring point together with a few other team members.
11:06He is eager to share the valuable experience he gained 15 years earlier.
11:21In 2005, Ren Xiu Wu collected the world's highest gravity data at the time.
11:50In doing so, he found a design flaw in his gravimeter.
11:57Ren Xiu Wu is only able to do this.
12:00It is a rope.
12:02You can just push it back and push it back and push it back.
12:05Or you can use a handkerchief.
12:07You can always push it back and push it back and push it back.
12:10Or you can use a handkerchief.
12:12Now, we have made a chain.
12:15We have made a chain.
12:18We have made a chain.
12:19It makes it easy to control the index.
12:25We choose a handkerchief too.
12:27We don't need to be using the back coat.
12:28We also need to prevent the fireствore.
12:30We are making the fireствore.
12:31We can make the fire草 or the damage we should.
12:35And then, we have implemented.
12:39Frostbite is a common hazard for climbers nearing the peak of Mt. Chomolongma.
12:57Zhang Weiqi is the youngest mountaineer.
13:00He is suffering from frostbite on his fingers during training for crossing the wind gap.
13:09His fingers are the most slow.
13:14So, in the low temperature, in the low temperature,
13:17especially in the cold weather, it's very easy to get off.
13:21It doesn't move away from the upper surface to the upper surface,
13:26to the upper surface, to the upper surface, and to the upper surface.
13:32Frostbite in its initial stage is not painful, only numb.
13:36Although Zhang Weiqi's condition has been spotted early,
13:41and has not damaged his soft tissue or muscle,
13:44he has been told he cannot continue to the peak.
13:59On May 19th, when there are only 12 days left before the end of the month,
14:04the mountaineering team finally received their instructions to proceed.
14:07Here we go.
14:37The 12 surveyors chosen for peaking depart from the 6,500 meter advance camp to continue
14:48climbing Mount Chomalungma along using ropes laid beforehand by the road building squad.
14:57It is a sunny day with sporadic clouds and snow, which is normal on Mount Chomalungma.
15:05With adequate supplies and capable mountaineers, everything seems to be going well.
15:35While the climbers chosen to peak are getting ready, down below, in front of the mountain,
15:45members of the intersection survey team have arrived at each of their designated points.
15:50This is the river in the river.
15:56Now, because of the rain, we can't see the wind.
15:59This is the wind. It's only 11 kilometers.
16:01Every day, every day, every day, every day, every day.
16:03Every day, every day, every day.
16:05Every day, every day, every day.
16:07Every day, every day, every day.
16:09It's dry.
16:11It's like this.
16:12It's right.
16:13It's like we're planning on the 22nd of the year.
16:16It's a new year.
16:17It's a new year.
16:18So we're going to be at 23rd of the year.
16:22Okay.
16:23The fourth time we've been on.
16:28The surveyors arrayed in front of the mountain have installed their equipment ahead of time.
16:45Once the surveyor's beacon is erected on the summit, they will have to immediately begin their individual intersection measurements,
16:53from which the precise elevation of the summit will be derived.
16:57Intersection Survey uses the principles of trigonometry and geometry to measure landforms and terrain.
17:11The surveyors stationed at six observation points around the mountain will use their equipment there to measure the peak's angle of elevation,
17:18with which the height of the peak can be worked out.
17:22The surveyors will be combined to derive the 3D coordinates of the peak, which can then be incrementally revised to achieve a more precise number.
17:44On this day, Sering Semdrup, the vice-captain and coordinator of the mountaineering team, arrives at the expedition's communications tent early in the morning, anxiously waiting for news from the front.
18:05In a video call with the road building squad, he hears some bad news.
18:29Sering Semdrup, the
18:59Sering Semdrup will go.
19:01Sering Semdrup will go.
19:02Sering Semdrup will go.
19:03Sering Semdrup will go.
19:04Sering Semdrup will go.
19:05Sering Semdrup will go.
19:06Sering Semdrup will go.
19:07Sering Semdrup will go.
19:08Sering Semdrup will go.
19:09Sering Semdrup will go.
19:10Sering Semdrup will go.
19:11Sering Semdrup will go.
19:12Sering Semdrup will go.
19:13Sering Semdrup will go.
19:14Sering Semdrup will go.
19:15Sering Semdrup will go.
19:16Sering Semdrup will go.
19:17to open up a road on the ridge,
19:18the surveyors around the mountain
19:20have also been hit by snow.
19:23Heavy snow, which is rare in May,
19:26is now falling on the entire Mount Chomolungma region.
19:47In the morning there's a lot of rain here,
19:49but now there's no kind of rain here.
19:51There's a lot of rain here,
19:52but no one could see.
19:57The rain has got a little...
19:59the rain can finally freeze.
20:01But now we can never see.
20:04From the pale river,
20:06the grass hollows are above to the top,
20:07but it's not clear.
20:17A high-altitude cameraman filmed the ridge where the team was forced to turn back.
20:42It is as steep as a blade.
20:47When the team came back, usually the technique which was difficult for real life.
20:53It was quite a bit of a pressure, as well as the head was 80 degrees.
20:59Now when the eye is thrown out, it will not be stable, it will hang on the other side.
21:06During the outside is no longer.
21:09I never went up to the hill, and I was trying to do it.
21:14Under the hill is no longer.
21:16The ridge, at 8,000 meters in altitude, is fully exposed to the wind.
21:31Nobody in the history of climbing on Mount Chomalangma has seen snow there before.
21:46The road building squad, the Vanguard, is tasked with laying safety ropes to ensure that the surveyors
22:16carrying their measuring equipment can reach the peak.
22:32The team is forced to descend again.
22:46To keep up morale, Tsering Samdrop, the vice-captain, and other team members in the 6,500-meter advance camp come forward to greet them.
23:02Behind the words of comfort, everyone knows that time is pressing.
23:06Is pressing?
23:07Oh, it's all.
23:08Do you want to see?
23:09It's hard.
23:10Take it forward.
23:11Take it forward.
23:13Don't, don't, please.
23:14No, it's not.
23:15Yeah, don't.
23:16It's fine.
23:17Three of them.
23:18It's not easy.
23:19It's not easy.
23:20Thanks, the weather looks good.
23:21It's not easy.
23:22It's not easy.
23:23It's fine.
23:24Just go ahead and get money.
23:32This is the cavalry侑.
23:33That's the end of organizations
23:35This is the best
23:37Amazing
23:42They don't do this
23:45They've said we don't do this
23:47It went down to the top of the bottom
23:49It went down to the side
23:51They are in the group
23:53They are in the group
23:54And they are in the group
23:56They are in the group
23:58They are in the group
23:59They already have five or six
24:01You can't go to the weather.
24:03If the weather is not bad, you must go to the weather.
24:05You must go to the weather.
24:07You can go to the weather for 10 minutes.
24:09Really?
24:10You can go to the weather for 10 minutes.
24:12You can go to the weather for 3,300 hours.
24:15How long will you go to the weather for 10 minutes?
24:31Once you are waiting for a patient, you can go to the answering room.
24:40The last time is getting out of trouble.
24:42The first timing is getting to the
24:54other hours and periods.
24:58Weather monitoring shows that before the second attempt, the tropical cyclone Amphan had been moving toward Mt. Chomolongma.
25:15The mood in the camp hits a low. Nobody can tell when the storm will pass.
25:28We will see the situation tomorrow, but we will wait for them to eat.
25:32We will only be able to get out of 10 days later.
25:40When the storm came here, the storm came here.
25:44The storm came here. The storm came here.
25:48The storm came here. The storm came here.
25:52The storm came here.
25:54Descending from 7,790 metres, the team members wait anxiously in the 6,500 metre advanced camp.
26:04It's not clear how long they will continue waiting.
26:08Returning to base camp will mean the termination of the project.
26:14Since the beginning of May, the 2020 Mt. Chomolongma Elevation Survey has become a hot media topic, both in China and abroad.
26:22Preparations for the project took nearly a year.
26:29The first geodetic surveying brigade under the Ministry of Natural Resources set up its measurement control network around the Mt. Chomolongma half a year earlier.
26:38Finally, a total crew of nearly 200 people travel to work together on the mountain to support and conduct the mission.
26:4850 days have passed since the project start, and its headquarters is faced with a hard choice of whether to give up or keep going.
26:59I went to the
27:28The Rungbuk Glacier, made up of snow fallen over tens of thousands of years, is like a
27:43blue jade ribbon that embellishes Mount Chomolangma.
27:46It is a gift of nature, a pearl on the mountain.
27:56It flows slowly down along its valley, nurturing life below with its meltwater.
28:08The acceleration of this melting, however, is a bad sign.
28:19Chinese scientists have found chemical pollutants from South Asia in the ice of the Rungbuk
28:24Glacier.
28:31Environmental pollution and global warming are not only damaging the pristine glacier,
28:36but also leading to unpredictable weather.
28:50The end of May is approaching, and there are only 10 days left in the mountaineering season
28:55on Mount Chomolangma.
28:57As summer approaches, the Rungbuk Glacier will begin melting.
29:04The transportation of supplies may be blocked by its meltwater at any time.
29:09As the humidity rises, snowfall may be heavier and more frequent.
29:16for current conditions on the mountaineering scene, it is to be 0.5% from the spring area.
29:23If you compare those conditions with lair daunbuk Glacier, and the weather conditions are
29:25too few, as they remain in the mountains.
29:26The current conditions, the
29:43nearing team's next step.
29:47Since the second attempt at Peking,
29:49the Shigatse Weather Bureau has set up
29:51a temporary forecast station in the base camp
29:54of Mount Chomolongma.
30:13On May 24th, with only one week
30:39before the end of the mountaineering season,
30:41the cyclone Amphan is still hovering
30:43above Mount Chomolongma, with sporadic snowfall.
30:52The road building squad and transportation squad
30:55set out from the 6,500-metre advance camp
30:58for the North Cole ice wall again.
31:04Finally, it has been decided to give it another try.
31:13So, to catch the weather tomorrow,
31:15today, I want them to focus on the weather and the weather.
31:20The second time we won't lose, we won the 6500-year-old team.
31:27We won the second time, we won the second time.
31:31We won the sixth time.
31:34We won the second time.
31:36If we haven't lost our second chance,
31:39we won the second chance.
31:43If we haven't done this job,
31:46No matter whether it's a worker on the mountain or a worker on the mountain,
31:51it's a big regret for the future.
31:59Since China first conquered Mount Choumalangma in 1960,
32:03six surveys of the summit have been completed,
32:06among which two are well-known worldwide.
32:09In 1975, China erected the first surveyor's beacon on the mountain's peak.
32:20In this first precise altitude measurement project,
32:23it obtained a reading of 8,848.13 meters.
32:32Then, in 2005, China brought along a satellite positioning device and snow-depth radar.
32:39For the first time, it measured rock formations
32:44and calculated the peak's altitude to be 8,844.43 meters,
32:50a figure now inscribed on a monument erected at the mountain's foot.
32:58Will this time become another history-making event?
33:01We need to do it from 6,500 meters to 8,3 days.
33:09In these three days, we don't want to see a lot of bad weather.
33:14We have to push it over to the 27th or 28th of the day.
33:19If we can see a great weather in the bottom of the mountain,
33:23we will never reach the top of the mountain.
33:26We will never reach the top of the mountain.
33:36According to the weather forecasters,
33:38the cyclone Amphan is now moving away from Mount Chomalangma.
33:43But conditions have not yet cleared
33:45at either the 6,500-meter advance camp or the base camp.
33:57It begins snowing hard,
33:59and the forward team's safety is in doubt.
34:07On the second day,
34:08we reached the top of the mountain's foot,
34:10we started to catch the wind.
34:12From a smaller wind,
34:14and then slowly and slowly,
34:16we reached about 9 to 10.
34:18In the normal situation,
34:19when we were in such a big wind,
34:21there were no signs of the mountain.
34:22We could stop the mountain,
34:24and talk about the mountain.
34:26We would like to talk about the mountain.
34:28We would like to talk about the mountain.
34:29But the day,
34:30there was no sign of the mountain.
34:32You can see me,
34:33I can see you.
34:34And then,
34:35I will turn the mountain down.
34:36I will continue to climb the mountain.
34:38Finally,
34:52the forward team arrive at the 7,790-meter camp.
35:00They spend three hours setting up their tents
35:02amid a storm so violent
35:04that even their experienced alpine cameraman
35:07cannot hold his camera still.
35:37behind their smiles,
35:39everyone is aware of the dangerous situation.
35:59Selo orders his team members to sleep with their climbing boots
36:02and one-piece down jackets on.
36:04.
36:06.
36:08The other side is a fixed rod.
36:10We can put it on the ground or on the eye.
36:14But due to the big wind, the rod has a lot of tension.
36:18It may be cut off the rod.
36:21If the rod is set off, the rod is no protection.
36:25It may be from the other side to the other side to the other side.
36:28It may be thrown into the other side to the other side.
36:30If you really take off the ground and take off the ground,
36:34You don't have a long time for a long time.
36:44The last 200 meters are at the end of the tunnel.
36:47Yes, yes, yes.
36:49The last 200 meters are at the end of the tunnel.
36:57The last 200 meters are at the end of the tunnel.
37:01On May 26th, the wind and snow have yet to stop at the 6,500-metre camp.
37:18At 4 p.m., the road building squad sent back exhilarating news
37:22that a climbing rope has been laid to the top of Mount Chomalangma.
37:31To make more time for the main force to peak in survey,
37:53the road building squad have chosen to skip the 7,028 and 8,300-metre camps
38:00and complete their road laying within two days,
38:03a task for which four days were originally allotted.
38:06Because it's the last time, we're going to get to the 6th of the month.
38:11We're going to get to the end of the month.
38:13We need to get to the end of the month.
38:15We need to get to the end of the month.
38:19It's 2020.
38:21On May 27th, the road building squad sent to the 3,000-metre camp.
38:29At 2 a.m. on May 27th, the members of the Peking squad have hardly slept
38:45because of a lack of oxygen.
38:46It is still snowing when they set off.
38:50At base camp, correspondents and other crew members are also up early in the morning,
39:07waiting for news from the front.
39:09The 2020 Mt. Chomalangma Elevation Survey is approaching its critical moment.
39:25The team members are panting hard from a lack of oxygen.
39:30Going by their departure time, they should reach the top at 9 a.m.
39:40The sun has already risen, and the base camp has yet to hear from them.
39:48Time passes by, and the sky is still overcast.
39:53I'm standing there.
39:54I'm standing there in the side of the stairs.
39:56The people who want to meet me wouldn't be able to meet them.
39:59I'm standing there, standing there, standing there, standing there, standing there.
40:02And standing there, standing there.
40:03I am almost like a sadness.
40:06I've never met with many years.
40:09The team members of the team members, including the leaders of the Peking squad,
40:14the team members of the team members, including all the people.

40:19In the normal situation, we can be able to reach the top of the mountain.
40:26We can be able to reach the top of the mountain.
40:29We can be able to reach the top of the mountain.
40:42Although the members of the mountaineering team have received professional physical training,
40:46they have been constantly hampered by frequent snowfall since arriving at Mount Chomalangma.
40:53A month of living at high altitude and two attempts already made at peaking have drained their strength.
41:04Every step they take costs them many times more energy than it would at normal altitude.
41:16All the street and went south to the mountain,
41:23and turned on to the mountain.
41:29The radius of the mountaineering team will reach the bottom.
41:33It was a forceful of the mountaineering team to reach the mountaineering team.
41:37They hope to reach the mountaineering team.
41:40The mountaineering team is not treated well.
41:44Now our team is in this place.
41:47How long is it 15 minutes?
41:50It won't be over half an hour.

42:58What's the same?
43:00What's the same?
43:02The next half is close to the right now.
43:04The next half is close to the left.
43:06I think there's a lot of time to reach the center.
43:08How long have you been to reach the center?
43:10The second half is close.
43:12Okay, okay, that's okay.
43:19We'll wait for you to get to the top of the window.
43:23Okay.
43:25The cloud on Mount Chomalongma is dispersing.
43:43High-power telescopes and super telephoto lenses
43:46are focused on the peak.
43:48Suddenly, a few red dots come into sight.
43:56The surveyors are approaching the summit.
44:18The cloud on Mount Chomalongma is in the middle of the tunnel.
44:47I'm not going to let you go.
44:49I'll go.
44:51We got a help.
44:53We got help.

45:09Let's go!
45:39At 11 a.m. on May 27, 2020, the Chinese 2020 Mount Chomolongma Elevation Survey Mountaineering
45:48Team finally peaks.
45:59Luckily, by the time its surveyors are setting up their equipment, the weather has cleared,
46:04allowing for a smooth measuring process.
46:09At the highest point on Earth, Chinese surveyors finally erect the beacon they have prepared.
46:39For the first time, they also use a Beidou Navigation Satellite Signal Receiver to complete
46:47a GNSS measurement, while also assembling a snow depth radar on the summit, and using
47:01a gravimeter to obtain the world's first gravity reading taken on the Mount Chomolongma Peak.
47:13They remain at the top for two and a half hours, setting a new Chinese record for length of stay
47:19at the top of the world.
47:32Later, in a joint effort by experts from China and Nepal, all data collected is processed to
47:39calculate the precise height of Mount Chomolongma.
47:49On December 8, 2020, Chinese President Xi Jinping corresponds with Nepali President Bidya Devi Bhandari
47:57for a joint announcement putting the latest measurement of Mount Chomolongma at 8,848.86 meters.
48:05On May 27, 1975, Chinese scientists climbed and surveyed Mount Chomolongma for the first time.
48:22On May 27, 2020, the mission is accomplished again.
48:26Four and a half decades have passed.
48:38Technological progress is enabling measurement with much greater precision.
48:46The mountain, however, remains as it has always been, a symbol of the ultimate in human achievement.
48:56The mountain, however, remains as it has always been, a human being what Dafür is a도�� shouldn't be because of itsRETTYors,
