As for Xiahou Mingjie's achievements in the field of geomantic omen in Zhouyi, I personally feel quite powerful. It is easy for anyone to believe and understand Yi-ology from a scientific point of view, and it has also hit some "fake masters" in the market.
Moreover, he is also a famous director of the "International Yi-ology Federation". It is in this capacity that I think he has made great achievements in Yi-ology.
