China uses a single time zone, China Standard Time (CST, UTC+8), for the entire country despite spanning roughly the same east-west distance as the continental United States. The US uses 4 time zones; geographically, China would warrant 5. This was a deliberate political decision made in 1949 to reinforce national unity under a single Beijing Standard Time.
The practical consequence: in Xinjiang (far west China), the sun rises at 10 AM or later by the clock during winter, and sets after 10 PM in summer. Many Xinjiang residents informally use "Xinjiang time" (UTC+6, 2 hours behind Beijing) in their daily lives, but all official business, transportation, and media use Beijing Standard Time.
