Hong Fan has eight policies, and food is the top priority. The issue of food is not only a major concern of the country, but also a concern of the people. Entering the land of Fujian today, there are thousands of rice waves on the plains, fragrant tea and fruit in the mountains and forests, and crisscrossing fishing boats on the sea... "The concept of grain as food now replaces the old concept of grain as the main focus" and "singing mountain songs while eating on the mountains, reciting the sea classics while eating on the sea". For over 30 years, cadres and masses in Fujian have always kept in mind their instructions, under the scientific guidance of the Big Food Concept, to steadily develop grain production, cultivate and form characteristic industries such as livestock and poultry, fisheries, vegetables and fruits, tea, and edible fungi, vigorously develop facility agriculture, continuously break through the limitations of grain sources, and achieve significant results in building a diversified food supply system. Concept guidance: "Establishing a big agricultural concept and a big food concept" Ningde in eastern Fujian, with many mountains and vast seas. Fujian is known as "eight mountains, one water, and one field", and for a long time, the per capita arable land area has been less than a quarter of the national average.

On the dining table of people in eastern Fujian, there are two types of food for a long time: first, "sweet potato rice", which is the shredded sweet potato that is then dried in the sun as food; One is the large yellow croaker, a unique marine fish in China, commonly known as "yellow croaker" or "cucumber fish". The story of the big yellow croaker is deeply remembered by Liu Jiafu, who is over eighty years old. At the end of 1988, Liu Jiafu, who was then the head of the Ningde Aquatic Technology Promotion Station, submitted a report on the development of aquaculture technology for marine fish in eastern Fujian. "This instruction has given Fujian yellow croaker a new opportunity," Liu Jiafu told reporters. Afterwards, he led the research and development of batch breeding technology for large yellow croaker and achieved success
