Different dry and wet areas have different effects on our production and life. Give examples.

The dry and wet areas in China are divided into four situations: humid, semi-humid, semi-arid and arid. It has a great influence on our transportation, agriculture, diet and architecture. Such as; Due to more precipitation and numerous rivers and lakes, aquatic products, paddy fields, rice and water transportation are relatively developed in humid areas, with paddy field agriculture as the main industry. The building is simple and elegant, the roof slope is steep (precipitation needs drainage), and folk sports include dragon boat boating and swimming. In the arid areas of northwest China, because of less precipitation, there are many rivers flowing in and the flow is less. There is a serious shortage of water for production and living. Agriculture develops irrigated agriculture, mostly dry crops, such as wheat, cotton, sugar beet, melons and fruits. There are many bungalows. Traffic is dominated by roads and railways, and it is almost impossible to develop water transport. Others simply say that they are in semi-humid areas; Mainly dry land agriculture and dry crops, such as wheat, cotton and peanuts. The slope of the roof is smaller than that of the wet area. Semi-arid areas with roller skating: grasslands are the main areas, so agriculture mainly develops animal husbandry and so on.
