How many meters above sea level is the downtown area of Changdu? Will it be hard to smoke?

I would like to ask how many meters above sea level in Changdu city, will it be difficult to breathe? The average altitude in downtown Qamdo is 3,200 meters, making it difficult to breathe. The elevation of Qamdo City is 3200 meters on average. Low temperature and low oxygen content in the air will cause difficulty in breathing. Every year in Changdu City, from the end of 65438+February to the next spring, the mountains are closed by heavy snow, and there is a shortage of consumables. The medical conditions in hospitals are limited.
