In the early days of the People's Republic of China, society developed rapidly, but its economic capacity was limited. Basically, corn, sorghum and other crops are the main crops, supplemented by vegetables, and meat is occasionally found. Ten years of unrest has reduced the country's productivity and the food level has not improved. After 79 years of reform, agricultural production has jumped to a higher level, food has become rich, white flour (wheat) has gradually become a commonplace, and meat can often be eaten at the table. After 90 years, the national economy has jumped in an all-round way, and meat is no longer a rarity. People began to eat wild animals (including wild animals, which are illegal) and seafood. Now it is basically rice, white flour, meat, aquatic products and so on.
