Xuankong Feng Shui Master of the Song Dynasty, whether Feng Shui determines whether mountains or Qi are the main ones

Feng shui masters of the Tang and Song Dynasties focused on shapes and mountains when looking at feng shui. Later, in the Yuan and Ming Dynasties, some people began to summarize and apply numerology theory to Feng Shui, but generally speaking, the main focus was on form and mountains, supplemented by regulating Qi. Even the ancestor of Xuan Kong Xue, Jiang Dahong, said that when looking at Feng Shui, you must first observe the Longzhen Cave, and then use flying stars to cut it. Poor Feng Shui masters who are now practicing Xuankong, waiting for work, just sit at home and get the Yuan Yun Feng Shui to read Feng Shui. They are simply deceiving themselves and others.
