Does daylight saving change China to JST?
China Standard Time does not move its clocks at all, so its UTC+8 offset holds every day of the year.
Japan Standard Time does not move its clocks at all, so its UTC+9 offset holds every day of the year.
Is China ahead of or behind JST?
China is behind JST by 1 hour: when it is 12:00 pm in China, it is 1:00 pm in Japan. Neither China Standard Time nor Japan Standard Time observes daylight saving, so the abbreviations never change and the gap between them is fixed.
China Standard Time covers one zone for the entire country, and a different CST from the American one. Japan Standard Time covers Tokyo, Osaka and the whole of Japan. The identifiers behind them are Asia/Shanghai and Asia/Tokyo, which is what any calendar or scheduling system should be storing rather than a fixed number of hours.
