I want to know the history of Sandun.

Sandun ancient town has a history of 1500 years. It is the blood of Xixi culture and Liangzhu culture, with dense water network and prosperous five industries. It is called the land of plenty, the land of silk and the land of flowers and fruits. It is a typical water town in the south of the Yangtze River, with profound historical and cultural accumulation and rich cultural heritage of the ancient town. Sandun Town, with its dense water network and vertical and horizontal rivers, is known as the land of plenty, the house of silk and the land of flowers and fruits. Rich "water resources" have created a profound "water culture", and there are many historical allusions and legends about the origin of Sandun independence.

Sandun, also known as the famous mountain pier, was called Shandun when Weichi Gong recruited troops to stay in the pier during the Zhenguan period of Tang Dynasty (AD 627), and the "tributary of Taixi" was connected by Sam as a pontoon bridge. On the other hand, Sandun is an ancient water town, named after three mounds on the water: Wenxing pier, Dengcai pier and Shuiyue Lake pier. Wenxingdun is located in Guandi Temple, Henan Province, southeast of Wulitang. There are two stone bridges, Wenjing Star Bridge and Wuxing Bridge, which cross Orange Banqiao into Yangjiawan, Wenchang Pavilion in the east and Zhu Zhu Temple in the west. It is a treasure trove of geomantic omen, and there is an allusion related to Zhu Yuanzhang in the Ming Dynasty: Zhu Yuanzhang was wary of the treasure trove of geomantic omen, so he broke geomantic omen everywhere. Once Liu Bowen went to Sandun, he stood in front of Guandi Temple and saw that Yangjiawan was a square official hat and Zhu Zhu Temple was a jade hat with a jade top. Liu Bowen thinks that this place is a treasure trove of geomantic omen and needs an official. Therefore, the satellites bridge and the five-star bridge were built here, which broke the feng shui of this place. That's not enough. He believes that Gengjiaba needs a shield hand, Nanyang Dam needs a prime minister, and Wulitang needs thugs (military officers). In order to break the feng shui in these places and keep Zhu Yuanzhang's official position, he sent 749 people to Gengjiaba to learn to wear hats, and changed the place name to Hat City, because hats are like "shields". Nanyangba sent 749 people to learn how to make tofu skin, because tofu skin is like a piece of paper. Wulitang sent 749 people to learn how to make vermicelli, and fans beat their hands all day to symbolize thugs. Therefore, at the end of Yuan Dynasty and the beginning of Ming Dynasty, the hats of Sandun Maocheng were exported to Guangdong and Fujian. Nanyangba bean curd skin, yellow as wax and thin as cicada wings, is exported to Shanghai and Ningbo. Wulitang vermicelli is very famous and has become a bowl of famous dishes on the Chinese New Year table of Sandun people. There are many such legends. With the comprehensive renovation of Sandun Town and the expansion of the construction scope of Sandun New District, it is of great significance to excavate Sandun's "water articles" and give full play to the role of "water resources" in Sandun Town renovation, bridge construction, river regulation and new rural planning, so as to enhance the taste of Sandun New District and promote the development of Sandun water town tourism.
