What are the traditional foods in China?

An ancient book by China, Huangdi Neijing, describes the food structure of China people in this way: "Five grains are the supplement, five fruits are the help, five animals are the benefit, and five dishes are the supplement." Cereals, fruits and vegetables are all plant foods. Grain crops were called "five grains" or "six grains" in ancient times, generally including millet (also known as "yellow rice", with fine grains and yellow and sticky color), millet (that is, millet is known as "the length of five grains" today, and millet and millet are the main grain crops in northern China in ancient times), wheat (including barley and wheat) and glutinous rice (the general term for beans). Millet and millet are both plants originated in China and spread to Europe in prehistoric times. Rice and wheat are not native crops in China. It is generally believed that rice originated in India and Southeast Asia, and the earliest rice cultivation in the world was found in the early Neolithic cultural sites in China. Wheat originated in Central Asia and West Asia, and was introduced to China from the northwest in the Neolithic Age. In addition, sorghum is also a native crop in China, which spread to India and Persia (now Iran) in the 1 century. In China, every Spring Festival, people will use this idiom to wish the new year peace and prosperity. It can be seen that in this big country where "food is the most important thing for the people", grain production has had special significance since ancient times.
