TIL: All of China has the same time zone.

It's because the majority of the population lives in the east of China, so they don't really care whether or not the western side is inconvenienced by being the "wrong" time.

Though it's also worth noting that in more rural or pre-industrial areas the precise time of day is rarely all that important anyway - a farmer is going to be more focused on things like "dawn", "noon", and "sunset" than they are 3:42pm. So less developed areas are mostly ignoring the official time anyway in favor of environmental prompts.

Precise times are more important for people involved in business (especially global business), or where you constantly have to meet with specific people at specific times in specific places, where coordinating is key. A peasant farmer in the middle of nowhere is never going to need to know the time down to the hour, let alone to the minute or the second.
