Talk about the morning and evening differences between the eastern and western ends of China and the seasonal differences between the northern and southern ends, and explain the reasons.

The difference between the east and the west in the morning and evening is mainly caused by the difference in longitude between the east and the west, which is related to the time zone. Every 15 is a time zone. The whole earth has 24 time zones, and we in China account for 5, each time zone is one hour apart. In China, Beijing time, namely GMT+8 time, shall prevail. Therefore, the eastern and western regions of China,

The reason for the seasonal difference between north and south is that China spans 49 latitudes, from Zengmu shoal (near 4° N), the southernmost part of South China territory of Nansha Islands in the South China Sea, to the center line of Heilongjiang main channel (53 N), the northernmost part of North China territory north of Mohe River in Heilongjiang Province. Subtropical monsoon and a small amount of tropical monsoon dominate in the south, while temperate monsoon and continental monsoon dominate in the north. The seasonal difference between the north and the south of China is roughly manifested as "four distinct seasons in the north and dry season and rainy season in the south", which is the concrete manifestation of climate difference.
