The Last Strange Door

The so-called Qi Men Jiu Gong is related to the heavenly stems, which is nothing more than "wearing nine shoes, three on the left and seven on the right, two and four are shoulders, six and eight are feet, and five characters are in the middle." If you want to break the game, you must first measure the ten games of yin and yang. The yang game is pushed forward and the yin game is pushed backward. For example, if it is the fourth round of Yin, then move from the word Wu to the fourth position, which is also the northwest of the nine palaces, and then reverse it: Si Wu, San Ji, Er Geng, Yi Xin, Jiu Ren, Ba Kui, Qi Ding, Liu Bing, Wu Yi. This is a normal arrangement of the four heavenly stems and nine palaces of Yin inverse.
