Lhasa, known in Tibetan as "the place where gods and buddhas live", is a famous historical city in Tibet and also the political and cultural center of Tibet. As a famous plateau city, Lhasa is also called "Sunlight City" because of its unique sunshine concern.

Lhasa has a long sunshine time, with an average of 8 hours 15 minutes per day. It is almost half that of other areas at the same latitude and twice that of Sichuan Basin.

Tibet's high altitude makes it closer to the sun than other cities. The higher the altitude, the thinner the atmosphere and the smaller the air density. In addition, there is little pollution in Lhasa, and the weather is fine all year round, so Lhasa has sunshine all year round.

Although the sunshine is long, there is also a lot of rain in Lhasa, mostly between 8 pm and 8 am the next day. The sun was still shining after the rain, and the weather was fine the next day. The sunshine is so abundant that it is not an exaggeration to call Lhasa "Sunshine City".
