During the daylight saving time, the time changes and the time zone name changes.

Answer 2

China has only one standard time.

The time in china tends to follow a specific standard time offset of UTC + 08:00 despite china spans over five geographical time zones.

The official standard time is known as Beijing time and the china standard time internationally.

However, the daylight saving time has not yet observed till 1991.

The special administrative regions tend to maintain their own times with standards.
