Are rice and wheat mainly distributed in monsoon region or non-monsoon region in China?

Rice and wheat in China are mainly distributed in the monsoon region. In the northern temperate monsoon climate zone, the plain is vast and there are many cultivated lands, but the heat is low and the precipitation is less, mainly in dry land, and the main food crop is wheat; The southern tropical and subtropical climate zone is hilly and mountainous, but it has high heat and abundant precipitation, mainly paddy fields, and the main food crop is rice. Therefore, rice and wheat in China are mainly distributed in the monsoon region. In the eastern monsoon region of China, the rain and heat are in the same period, the soil is fertile and the productivity is high, and about 90% of the cultivated land and forest land in the country are concentrated.
