Is Yuan Fa Li Yuan a true master of the Book of Changes or a liar?

Teacher Li Yuan is the founder of Yuanfa, a practical expert in Feng Shui, and a practitioner of China traditional culture who has studied the Yijing for decades. The original seven-dimensional integrated technology that has been tested in practice has helped many people and has an extraordinary position in the industry. I participated in his offline course and experienced the top technology of Zhouyi traditional culture for the first time, and my position is beyond doubt.
