Is Wang Zanghai a real person?

Yes This person did exist in the history of Wang Zanghai, but was later adopted by others, so it was renamed Wuzhong. He was a famous geographer, architect and Feng Shui master in Ming and Qing Dynasties. Judy, the founding emperor of the Ming Dynasty, moved the capital to the Forbidden City, which was a major project he participated in designing and presiding over. Wang Zanghai was born in an ordinary peasant family, and his father was a carpenter. Since the second son and distant relatives in the family were middle-aged and childless, he begged his father to adopt a child to the Wu family. The Wangs had to adopt their second son, who couldn't remember at that time, to the Wu family, so they changed their name to Wuzhong. The Wu family is well-off, so Wuzhong studied in Japan in his early years. By chance, he came into contact with Yin and Yang Feng Shui, which was lost after the "An Shi Rebellion" in the Tang Dynasty. He was born with genes. Wuzhong loves architectural geomantic omen very much, studies it thoroughly, and learns by himself, and has accumulated high attainments in geomantic yin and yang.
