The advantages of agricultural production in Tangji mainly include

Tangji model is a traditional low-lying land utilization model that farmers in the Pearl River Delta began to use more than 600 years ago. After farmers dig ponds and lift fields to form foundation ponds, they plant mulberry on the foundation ponds to raise silkworms, put silkworm excrement into fish ponds to raise fish, and return pond mud to the fields to fertilize mulberries. "Silkworms can make fish fat." This is the traditional Sanji fish pond.

The foundation pond model adapts to the environmental change of labor force to industry, and changes from labor-intensive production to low labor-intensive production. Adapt to the changes in the price environment and change from low-value products to high-value products. Adapt to the improvement of traffic conditions and the needs of urbanization development, change from transportable and storable products to fresh products. Adapt to the conditions of strengthening farmers' investment ability, gradually increase commercial investment and increase commodity output at the same time. To meet the market demand for products, the ratio of base surface to pool surface has changed. However, the foundation pond model has always maintained the basic characteristics of making full use of the rich water resources in tropical and subtropical monsoon regions, combining planting and breeding, reducing soil erosion and returning pond mud to the field. The foundation pond model can adapt to the environment.
