Use.
The capital of China is Beijing.

The time zone UTC+08:00 matches the visual sun time for 120° east.
The complete hour UTC+08:00 is a compromise to be compatible to other time zones on earth.
Because Beijing is the capital, and the UTC+08:00 time zone is about right for the capital’s location, people usually call China Standard Time, , in English Beijing Standard Time (BJT).

Many locations north and south of Xinjiang use this time zone.
However, the main population, the Uyghur people, also use the time zone as a political statement, to express disagreement with the central government in Beijing.
