What is the relationship between neighborhood and geomantic omen in Ming Dynasty?

In Ming Dynasty, Nanjing paid attention to geomantic omen. There was a neighborhood called Shimaofang, also called Baimaofang, which was located in Cai Xia Street food market in the south of Shengzhou Road. There is a memorial archway here, which was built by Guo Gong in Tonghai in the Ming Dynasty. According to legend, after Emperor Zhu Yuanzhang of the Ming Dynasty proclaimed himself emperor, Yu Tonghai, Yu Yu and Yu, who fought side by side with him, were all named Hou and Gong because of their outstanding exploits. After Tonghai's death, he was posthumously named the loyal Duke of Guo and built a palace for his descendants. However, there are also people who do wrong in Shi Yu's life. They accused Yuzhai of "kingliness" in front of Ming Taizu, and Zhu Yuanzhang himself believed in Feng Shui, so he asked Liu Bowen to break the "kingliness". Liu set up a memorial archway in front of Yu's house, carved hundreds of cats on it, hence the name "Hundred Cats Square". Because it is carved with white stone, it is also called White Cat Workshop or Stone Cat Workshop. A well will be dug in front of the factory building, and a gate post will be set behind the house. Diaoyutai is located in the east of the house, and Fish Lane is located in the west of the house. It is said that this is the "Eight Diagrams Array" to break the "Imperial Soul". There are still some remains on the road here today. There are four pillars and banners in that stone cat workshop, and the carved stone cat is still there.
