"Thirteen Taboos of Yang Gong" has been valued by Xuankong since ancient times. In Xuankong's eyes, these thirteen days can never be chosen as the days of opening, construction, marriage and signing contracts.

Cultural significance:

Yang's geomantic theory mainly embodies the idea of peaceful coexistence between man and nature. In the theory of geomantic omen, he advocated taking Luan Tou as the first priority, emphasizing local conditions and choosing acupoints according to dragons. Yang Gong's geomantic theory works, such as Shake the Dragon Sutra, Doubt the Dragon Sutra, Qingnang Sutra, Tianyu Sutra and Yuchi Sutra, have been handed down from generation to generation, leaving a lot of detailed written materials and physical heritage for the study of ancient geography in China.

Yang Gong's geomantic omen inherited the essence of Guo Pu's geomantic omen, emphasizing the organic combination of dragon, water and direction, paying attention to the coordination of dragon and hall qi in regulating qi, taking 72 dragons as the core, taking qi as the auspicious, taking advantage of the vigorous dragon qi as the auspicious, taking the gas as the evil, and destroying the dragon qi as the good or bad of the big palace of Yin and Yang depends on whether you are angry with the dragon that can ride vigorously and whether you can reasonably.

According to Yang Gong's geomantic theory, the dragon god should coordinate with the "sitting on the mountain" of Yin and Yang houses, and the coming and going of water should coordinate with the "orientation" of Yin and Yang houses, which is also the main principle of Yang Gong's geomantic theory. During his settlement in Sanliao Village, Meijiao Township, Xingguo County, Yang helped the poor, wrote books, taught students, built houses and repaired tombs, so that geography and culture could be handed down to the world for future generations to study.
