What is the oxygen-breaking layer?

Oxygen-breaking layer refers to the lack of oxygen at high altitude, so it is called oxygen-breaking layer. For example, maduo county is located in the "oxygen shear layer" at an altitude of 4,300 meters. It is cold and anoxic all the year round, and needs heating for 1 1 month in a year.

The average altitude of Golog Prefecture in Qinghai Province is 4,200m, and that of maduo county is 4,300m. It is a well-known oxygen-broken layer on the Qinghai-Tibet Plateau, with thin oxygen and unpredictable weather, and four seasons can be seen in one day.
