Food security is the important foundation of national security. Chinese people have been self-reliant in ensuring their own food security since the founding of the People’s Republic of China more than 70 years ago. Not only have the food problems of over a billion people been solved, but the quality of life and nutrition of the residents have also been significantly improved. In recent years, as the yield of rice and wheat has satisfied the domestic needs, China has basically achieved self-sufficiency in grain, with food imports meeting the domestic consumption needs for diversity. Gone are the days when we didn’t have enough to eat.
