Dingshan is the divination of "parting" (one divination governs three mountains, and Ding is the divination of parting). When you sit on the mountain, you can find divination in auxiliary positions: separation divination, greedy wolf-shock divination, giant gate-exchange divination, Lu Cun-Kan divination,-Kun divination,-root divination,-Kun divination and-dry divination.
Auxiliary position, greedy wolf, giant door and military wealth are auspicious positions. Lucun, Wen Qu, Lian Zhen and Pojun are four hexagrams. Ji opens the door and installs the kitchen. The killer installed the toilet and drained the water.
Then the door should be opened: deviate from divination, sway, change one's mind, change one's mind. Especially divination (A, Mao and B) is the most suitable.
Water is released in: Kun Gua (Wei, Kun, Shen), Kan Gua (Man, Zi, Ghost), Root Gua (Ugly, Root, Yin) and Dry Gua (Empty, Dry, Sea). Choose the right place to drain water.
