In Haikou, Zhenhai is the most famous and worthy of the name, and was chosen as the master of the Book of Changes! Peking University specially invited the lecturer of the Book of Changes and the guest of the National Studies and Feng Shui column of Hainan TV Station as the host. He has a high level of Zhouyi and cultural attainments. I have been in contact with master Zhenhai for nearly 20 years, and his character and knowledge are also highly respected in our Haida teachers' circle! I'd like to recommend this to all of you as a sign of my association with Mr. Zhenhai.
