🇨🇳 Guangzhou

Set on the Pearl River delta in southern China near 23 degrees north latitude, Guangzhou is a major coastal city of roughly 16.1 million residents. It runs on China Standard Time, the nationwide UTC+8 offset, and applies no daylight saving, so its clocks stay eight hours ahead of Coordinated Universal Time across all seasons. The city lies close to the Tropic of Cancer in the Northern Hemisphere, where day length changes little through the year. Sharing a single official time with the rest of the mainland, Guangzhou reads the same hour as the northern capital and cities on the far western frontier, despite the considerable east-west distance the unified zone spans.
