Shen Wansan (said to have been born in 1296, and two others are said to have died in 1330 and 1328), whose real name is Shen Fu and whose real name is Zhong Rong, is commonly known as Wan San, a businessman in the late Yuan Dynasty and early Ming Dynasty. Shen Wansan accumulated primitive wealth by developing overseas trade, making him the richest man in the south of the Yangtze River, with "millions of assets and land all over the world". Zhouzhuang's "changing villages into towns" is also a credit to Shen Wansan. As for the rich man in Shen Wansan, he even said that he had a cornucopia and so on, which reflected that his wealth was countless and his skills in making and accumulating wealth were superb. Up to now, many stories and legends about Shen Wansan's wealth, luxury, real estate, business and family life are still widely circulated in southern Jiangsu, northern Zhejiang and Anhui.

According to folklore, Shen Wansan has a cornucopia. If you put in a golden hairpin, you can take out a handful of golden hairpin. Put in a silver ingot, you can take out a pot of silver ingot, which is inexhaustible, so it can be rich in the world. In Nanjing, he built walls and related facilities for Zhu Yuanzhang, and also built 1654 cloisters and four restaurants, which cost countless dollars. Xuanwu Lake Park in Nanjing today is the former site of his back garden. The luxurious banquet and rich costumes are beyond people's imagination. His agate hip flask is bright and crystal-like. There is a grape in the middle, called the grape under the moon. It is said that it can be exchanged for "Jiaxing County Salt Banknotes".
