Litang, the City in the Sky.

Known as the world's highest city, Litang is also called the City in the Sky, mainly because of its high altitude, with an average altitude of over 4,000 meters. It is said that most people don't feel much at an altitude of about 3,000 meters, but you need to be careful when you're over 4,000 meters. Walk slowly and remember not to run. The Litang government has done a great job here, with reasonable planning and regulations. This is where the 7th and 10th Dalai Lamas were reincarnated. The 6th Dalai Lama, Tsangyang Gyatso, wrote about this place in his poems. It is also the hometown of Ding Zhen. However, when I went to Litang, Ding Zhen was not yet famous. Take a stroll around the county, look at the neat streets, and see the photos of Tibetan customs hanging on the walls. They are very pure and simple. There is a carpet weaving workshop, and the Tibetan girls are very kind. They even taught me how to weave a carpet, which is not easy. Tibetan wool carpets are made of real materials, and the woven carpets are particularly thick. People should go far and wide when they are young, see and feel more, and experience different lives.
