China is 5 hours faster. The local time in Moscow is the East 3rd District time, and the local time in Beijing, the capital of China, is the East 8th District time. The difference between Beijing time and Moscow time is 5 time zones, and one time zone is one hour, so the difference between Beijing time and Moscow time is 5 hours.
The longitudes of various regions and countries in the world are different, and local time is also different. The official time zone division, which includes 24 time zones, each time zone is represented by an English letter. A time zone is divided every 15° of longitude, with one exception. Each time zone has a central meridian; for example, GMT belongs to the "z" zone, so the suffix "Z" is usually added to its time (the suffix "Zulu" is used in colloquial language).

In order to overcome time confusion, at an International Longitude Conference (also known as the International Meridian Conference) held in Washington in 1884, it was stipulated that the world should be divided into 24 regions. Time zones (12 time zones for east and west). It is stipulated that the United Kingdom (the former site of Greenwich Observatory) is the middle time zone (zero time zone), East 1-12 zones, and West 1-12 zones.
Each time zone spans 15 degrees of longitude, and the time is exactly one hour. The final east and west districts 12 each span 7.5 degrees of longitude, bounded by 180 degrees east and west longitude. The time on the central meridian of each time zone is the time uniformly adopted in this time zone, which is called zone time. The time difference between two adjacent time zones is 1 hour.
For example, the time in East District 8 of China is always 1 hour ahead of the time in East District 7 of Thailand, and 1 hour behind the time of East District 9 of Japan. Therefore, people traveling abroad must adjust their watches at any time to be consistent with the local time. When walking westward, every time you pass a time zone, you must set your watch back one hour (for example, from 2 o'clock to 1 o'clock); when you go eastward, every time you pass a time zone, you must set your watch forward one hour (for example, from 1 o'clock to 1 o'clock). 2 o'clock). And it is stipulated that Britain (the former site of Greenwich Observatory) is the prime meridian, which is the zero degree longitude.
