    China will cut the number of climbers trying to climb Mount Qomolangma from the north this year as part of plans for the clean-up on the world's highest mountains. The clean-up activity will include moving away the bodies of climbers who died at more than 8,000 metres up the mountain.

The total number of climbers trying to reach the top of the world's highest mountain from the north will be controlled to less than 300. The climbing season will be controlled to spring.

Parts of Qomolangma are in China and Nepal (尼泊尔). Each year, around 60,000 climbers and guides visit the Chinese north side of the mountain, but few actually try to climb it. China has set up stations to sort (分类), recycle and break down rubbish from the mountain, which includes cans, plastic bags, tents and oxygen tanks (氧气瓶).

On the Nepalese side, mountaineering trip organizers have begun sending huge rubbish bags to climbers during the spring climbing season. They should collect rubbish that then can be carried by helicopters back to the base camp.

Every year there are many victims on Qomolangma often in the "death area" above 8,000 metres, where the air is the thinnest. In 2017, 648 people reached the top of Qomolangma. Six people have died on the mountain that year, one of whom on the north side.

Qomolangma has become the world's highest rubbish dump (垃圾场). Meanwhile, melting (融化) ice caused by global warming is exposing (暴露) rubbish that has been left on the mountain since Edmund Hillary and Tenzing Norgay made the first successful climbing 67 years ago.
