What is a strange door?

What does "Daoism" mean? It consists of three concepts: "strange", "door" and "hidden armor". "odd" refers to b, c and d; The "door" is the eight doors of rest, birth, injury, supervision, scenery, death, shock and opening; "Escape" means hiding, and "A" refers to six Jia family members, namely Jia Zi, Jia Xu,,, and Jia Yin. "Escape" is the most distinguished of the ten cadres. It hides but does not appear, hiding under the Six Instruments. "Six devices" refer to things, machines, watches, minds, people and ghosts. The principle of seclusion is that Jia and Liu Wu, Jia Xu and Liu Ji, Shen Jia and Liu Geng, Wu Jia and Liu Xin, Chen Jia and Liu Ren, and Jia Yin and Liu Gui. In addition, we also cooperate with Peng, Ren, Chong, Fu, Ying, Rui, Zhu, Xin and Qin Jiu. Taoist investigation is mainly divided into three parts: heaven, gate and earth, which symbolize three talents. Pan Tian's ninth house has nine planets, and the eighth house of Zhonggong (the second house of Zhonggong) has eight doors. The eighth house of the venue represents eight directions and stands still. At the same time, on the site, each house was assigned a specific odd number of musical instruments (B, C and D) (E, Ji, G, Xin, Ren and Gui). In this way, according to the specific time, the arrangement of six instruments, three unique skills, eight doors and nine planets, to measure the relationship, character and trend of things, and to choose the auspicious side, constitutes a unique category in China's mysterious culture-Taoism.
