Since the 18th National Congress of the Chinese Communist Party, the introduction of a new food security strategy has provided an important basis for ensuring national food security. And new ideas, thoughts and policies have been introduced and supplemented, continuing to enrich and broaden the connotations and boundaries of the road to food security with Chinese characteristics. This paper reviews the important achievements and significance of China's food security under the guidance of the food security strategy in the new era and sorts out the evolutionary path and the shift which characterizes the current food security strategy. China's food security strategy has undergone five major changes:from taking care of the overall food varieties to preserving the key varieties, from promoting output to strengthening production capacity, from pressing the production areas to making a concerted effort, from emphasizing quantity to improving quality, and from the production side to the whole chain. In terms of policy options, to promote further improvements in food security, we should start with the in-depth implementation of the strategy of storing grain in the land and storing grain in technology, improving the institutional mechanism of two positive aspects of farmers' grain cultivation and local food control, establishing a synergistic mechanism of food security and green development under the goal of double carbon, building a double cycle system based on domestic production and integration of international resources and establishing a comprehensive food security system led by the Big Food Vision.
