Cooked in North China?

North China usually plants two crops a year, that is, wheat is planted in winter (from the National Day to the next 24 solar terms) and corn is planted in summer (from the 24 solar terms to the National Day in summer).

Some people don't want to grow wheat and corn. For example, cotton can only be harvested once a year.

In the past two-year triple cropping system in Huaibei area, spring corn was used as the pioneer crop, wheat was planted after corn harvest, and summer soybean was planted after wheat harvest the next year, forming a two-year triple cropping system of pure dry farming.

So it's both.
