In China, rice production is an important part of the national economy.
As early as 4,000 B.C.，the Chinese started rice cultivation which later gradually spread all over the world.
At present, China is the world's largest producer of rice, producing 26% of the world rice output.
The rice crop in China grows primarily in provinces along the Yangtze River and in the South.
Rice is an important staple food for Chinese, particularly the Southerners.
In addition, rice can be used to make wine and sugar and used as industrial materials.
As one of the three major cereals, wheat is a kind of cereal crop widely planted all over the world.
China is one of the earliest countries to grow wheat，which has a planting history of more than 5,000 years.
At present, the main wheat producing areas are Henan province, Shandong province and Jiangsu province. According to different sowing seasons, wheat can be divided into spring wheat and winter wheat.
Wheat flour can be made into steamed bun, noodles and other food, which serve as the staple food for people in northern China.
Wheat has high nutritional value and is highly beneficial to health.
Cotton is one of the most important crops in the world which can be made into all kinds of fabrics. It has high yield and low production cost.
China is the world's largest producer of cotton. In terms of region, there are three major cotton producing regions in China: Xinjiang region, Yellow River region and Yangtze River region.
According to statistics, Xinjiang's cotton output in 2020 accounted for about 87% of the country's total output.
In fact, cotton is not a native crop in China. During the Qin and Han dynasties, the knowledge about cotton was introduced into China from India, and the Chinese word for cotton was also borrowed from Sanskrit.
