Introduction:
The cornucopia is a treasure in ancient folk stories in China. It is said that Shen Wansan became rich in his early days because he had a cornucopia. This allusion comes from Zhou's Collection of Different Lights: "At the beginning of the Ming Dynasty, when Shen Wansan was young, he saw a fisherman with more than 100 frogs, picked them up, bought them in an iron pot and raised them in a pond. Then the noise was so loud that I couldn't sleep. In the morning, I drove it away When I saw frogs surrounded by a earthen basin, I thought it was an instrument for washing hands. Three thousand wives left silver hairpin in the basin, and the silver hairpin was full and countless. The same is true of money and silver, so this is the wealth of the world. "
When Jubaomen was built in Hongwu period of Ming Dynasty, the foundation subsided and was repeatedly built, but it was still not built. Knowing this, Zhu Yuanzhang, the Emperor Taizu of Ming Dynasty, called the counselor to predict that there were monsters on the foundation of the city wall to eat soil and bricks, and that a cornucopia would be buried under the city gate to suppress it. Zhu Yuanzhang ordered the collection of Shen Wansan's cornucopia and buried it under the city gate, so it was built, hence the name "Jubaomen".
