Tianyu*

"Tianyu Jing" is the most important classic in Xuankong Fengshui and Qi regulation. It was written under the name of Yang Junsong. It was lost due to war. In the late Ming Dynasty, Jiang Dahong compiled the annotations and deciphered the difficult parts. From then on, Jiangxi Fengshui based on Xuankong Gua theory has been able to influence future generations for thousands of years. However, with the publication of Jiang Dahong's "Bianzheng of Geography", countless commentators successively commented on the "Tianyu Jing", and each person expressed his or her own opinion based on different understandings. For a time, pearls and jade were everywhere, and hundreds of flowers bloomed, making the students dazzled and at a loss as to what to do.
