Why didn't the first climber leave video evidence? What historical details are included in The Climber?

First, the first summit left no image evidence among climbers, but actually failed to leave strong image evidence. Because it was night when the summit was reached, the camera with China technology at that time could not guarantee the clarity of shooting at night.

When I went down to the summit, I also took two photos at an altitude of 8700 meters. Due to the limitation of the camera, it was also because the climbers spent a lot of energy in the harsh environment, and the photos taken were all blurred. And these vague and dark shots can't be strong evidence of the success of the summit.

Second, the historical details of climbers.

1, hiking shoes

Limited by technical conditions, hiking shoes at that time were made of whale skin, which was particularly heavy, which can also understand why the climbers in the film moved slowly. In addition, when traveling, you should always scratch your toes to keep blood circulation, otherwise you are likely to get frostbite, which will also affect your travel speed.

Step 2 group

Among climbers, climbers travel in groups and are connected with each other by ropes, usually in groups of four. Mountaineering in groups was the standard operation of the Soviet Union at that time. In order to prevent falling, but the result increased casualties, this method is not often used now.

3. Fossil

On the way to climb the mountain, Fang Wuzhou gave Xu a fossil of marine life obtained from Mount Everest. The area where Mount Everest is located used to be an ocean, that is, the ancient Himalayan sea. 1924, marine fossils were first discovered. However, the nine rock specimens brought back by the China mountaineering team for the first time are all Ordovician limestone.

Step 2

In The Climbers, there are many descriptions about the second step. The most difficult thing to climb Mount Everest from the northern slope is the second step, which is about 8600 meters above sea level. The British tried to reach the top from the North Slope seven times, but they never broke through. 1975, after the China mountaineering team set up a metal ladder here, the difficulty of climbing to the top of the north slope was greatly reduced, and more than 1500 climbers used the "China ladder".

5. The height of Mount Everest

In The Climber, it is mentioned many times that the height of Mount Everest is re-measured, and the target image is displayed. 1975, the China mountaineering team climbed to the top of the mountain with a 5 kg beacon, only to re-measure the height of Mount Everest. Previously, the British had measured the height of Mount Everest based on India. 1975, Chinese scientific and technological workers took the Bohai Sea as zero altitude, and the authoritative data was internationally recognized.

Extended data

Historical background of climbers:

Climbers are adapted from real historical events. In 1960s, in order to show China's national strength and national self-confidence. The government of China was ordered by the state to organize personnel to climb Mount Everest. It is estimated that as we all know, the peak over 8800 meters above sea level is a challenge to the limits of mankind.

At that time, the new China had just been established, everything had to be done, and the territorial division with Nepal was also put on the agenda. The biggest issue in this border negotiation is the ownership of Mount Everest. China claimed that the boundary line should be set at the peak of Mount Everest, and the ownership would be divided equally between China and Nepal. The Nepalese government disagrees, saying that China people have never climbed Mount Everest.

In order to defend territorial sovereignty, it is urgent to climb the top of Mount Everest. However, due to the economic tension and backward technology in New China, the joint mountaineering team proposed by the former Soviet Union was postponed due to the unexpected situation in Tibetan areas in 1959, and then China and the Soviet Union broke up. The Soviet Union has always shirked its mountaineering plan on the grounds of insufficient technical preparation. At this time, the significance of climbing Mount Everest is not limited to sports, but also involves the territorial sovereignty and international status of the motherland.
