The integrity of residential buildings is the knowledge of architectural environment planning and design in ancient China with a long history. Since ancient times, people have regarded site selection as the most important thing to live and work in peace and contentment. Its essence is to choose a vibrant land of geomantic omen, so that heaven, earth and people can be integrated, live in harmony and settle down. Although it seems that the geomantic omen theory has its historical limitations, it is even used by some Jianghu people as a tool to cheat money. However, as a cultural phenomenon and cultural heritage that has been circulating for nearly a thousand years, it still deserves our in-depth understanding, eliminating the rough and selecting the fine, eliminating the false and retaining the true, and drawing wisdom from traditional culture.
