First, the impermanence school Kong Xuan Feng Shui explained Kong Xuan in the most detailed way. Generally speaking, Xuan refers to the sky, indicating time, and empty refers to the ground, indicating space. Shen Shi believes that the metaphysical, one also, with empty, that is, know-how. There are nine orifices, so it is called nine orifices. This is the word Kong Xuan, from one to nine. One to nine, that is, the nine planets and metaphysics, that is, the concrete application of the flying principle of the nine planets in the geomantic compass. The theoretical basis is Jiugong Bagua and nine planets's technique, which have been popular since Qin and Han Dynasties. Impermanence refers to the place names of Wuxi and Changzhou in Jiangsu Province. This school is named after Zhang Zhongshan, a famous geographer who lives in Wuxi, Jiangsu. Feng Shui of Zheng Xuan's Empty Vessels was handed down from Guo Pu in the Eastern Jin Dynasty, including the Book of Burial and the Book of Clearing Capsule, to Qiu Yanhan and Yang Junsong in the Tang Dynasty, to Wu Kecheng of Chen Tuan in the early Song Dynasty, and to Wu Jingluan, a cold and modest lecturer in the late Yuan and early Ming Dynasties. In the late Ming and early Qing Dynasties, Jiang Dahong studied under Taoist Wu Tianzhu and Wuyi, and later he was followed by Fan Yibin, Zhu Xiaohe, Yin Yibao, Zhang Xinyan and Cai Minshan, and later he was spread to Wuxi in the Qing Dynasty. In modern times, he was followed by Shen Shaoxun, Kong Zhaosu, Tan, Wu, Shen Zumian, You Xuexing, Wang Tingzhi and Zhong Yiming. It took more than a thousand years from the Jin Dynasty to the Qing Dynasty until Shen Shaoxun published a book. In the mysterious geography handed down from ancient times, impermanence is the most effective
The geographical features of Metaphysics are based on the theories of Heluo, Taiji and Bagua in the Book of Changes, and there are many unique innovations in its application, which are quite different from other schools.
(A) the periodicity of time and space. Yuanyun is the soul of metaphysical geography, and its push to the earth is based on twenty years, sixty years and 180. So it is also called ternary metaphysical geography. Metaphysical geography holds that the movement of the earth is periodic, and the landscape and orientation of nature remain unchanged, but the gas flowing between heaven and earth is changing. The ability of this school to reveal the reasons and mysteries of the periodic changes of fortune is beyond the reach of other Feng Shui schools.
(2) Distinguish between good fortune and bad fortune with the stars of Jiugong. The geography of Kong Xuan uses the method of nine palaces approaching the stars to distinguish the ups and downs of mountains and surrounding landscapes. According to the situation, we can see the good or bad luck of stars meeting mountains and stars, so as to judge Ding, Cai, Gui, Xiu, Xian, Fool, Illness, Housing and so on.
(3) Compass is used in different ways. Generally, there are three compasses, the front needle (inner ring) is the site, the middle needle (middle ring) is the human disc, and the sewing needle (outer ring) is the top disc. The Three Rivers Sect used a straight needle to make the dragon stand upright, a middle needle to remove sand, and a needle to catch water. It is wrong for some people to stand upright with the middle needle and sewing needle. Kong Xuan geography always uses a positive needle. (Forehand is based on geomagnetic orientation)
