Answer:
Alot!
Step-by-step explanation:
The two sides of the Line have significant differences in climatology, vegetation, terrain, soil, and agriculture. The south is warmer and wetter in climate than the north of China. This is mainly because of the summer monsoons which move from southeast to northwest. Most of their moisture is left behind before they can reach the boundary line. The North China plain is relatively arid. These climate differences support different types of agriculture, with wheat (such as millet and maize) hence mantou (steamed bread) and noodles are the dominant staple in the north; while rice is produced and consumed more in the south. Vegetables in the south are a lot more abundant, as well as seafood.
