What kind of agricultural crop did the ancient Chinese grow?

The ancient Chinese cultivated: barley, millet, rice. The main among them, of course, was rice. The natural conditions of ancient China were very well suited for growing rice, as it required constant moist soil. In China, in those days, there were frequent floods of the Yellow River. It is also called the “Wandering River” in another way, as it often changed its course. This state of affairs often had negative consequences, for example, flooding settlements.
