How to calculate the vertical water intake of Fengshui Mountain 24 12 Changshengkou?

The Nashui compass uses (1) geographical compass relative to the site, and the sky disk rotates clockwise by half a grid angle relative to the site. The sky plate is used to receive water after searching for dragon sand, which is the gas bureau that defines the water potential of Yin-Yang and Five Elements-taking the raw side as the source, the flourishing side (also used for declining side) as the vertical side, and the tomb side as the nozzle. (2) Mountain 24 in Pan Tian is divided into 12 Shuang Shan: Renzi-Guichou-Genyin-Jiamao-Chen Yi-Xiangsi-Bingwu-Ding Wei-Shen Kun-Gengyou-Xinwei-Ganhai. Every Shuang Shan contains a earthly branch, and the trinity of earthly branches represents three directions of Wang Sheng's Five Elements Tomb. (3) The importance of receiving water lies in the local support of the three-in-one game. The three-in-one game is nothing more than the truth of the twelve longevity of Yin and Yang. A, Siyang Ganshou is in the four corners, the emperor is in the four positions, and the tomb is in the four dimensions. (Jia Mu/Hai, C Huo/Xu, Geng Jin/Si Youchou, Li Shui/Shen Shiye. ) b, Siyin Ganshou is in Sizheng, the emperor is in the four corners, and the tomb is in four dimensions. (Mu Yi/Wu Yinxu,/You Sichou,/Ren Kunyi, Gui Shui/Jia Ganding is also. ) Note: ① Shuang Shan is full of qi, and one word in the above-mentioned integration of three qi represents two words. (2) The living position of dry in the shade is the dead position of dry in the yang. (4) The 12 life position of Sanhe Bureau falls on the position of 12 Shuang Shan, so it also shows the 12 life stage of each Shuang Shan. Immortality-Bathing-Crown Belt-Pro-Official-Emperor Prosperity-Decline-Illness-Death-Tomb-Absolute-Fetion; Arrange clockwise according to the yang bureau and counterclockwise according to the yin bureau. (5) Use the venue to determine a certain direction of a mountain, and see which mountain this line passes through from the ceiling. The direction it passes through is the basis for judging which game it belongs to. For example: A, on the site, Zishan is at noon, C string is on the sky plate, Shuang Shan is at noon, the bureau is at noon, and the left water turns to the right, which is the gas of fire. B, Zishanwu, Xianwu, Wu Bing, Shuang Shan, with Yin Wu Bureau, left water right, and the gas of fire. Bingji, Renshan to Bingji, Chuansi, Xunsi, use the unitary ugly bureau, right water to left, Ding. D, dry mountain lost direction, string lost, lost third, the same ugly bureau, right water splashed left, Ding. E, Ganshan, Chen Chuan and Shuang Shan Chen Yi's tomb. Note: Chen Zhi is a tomb in the Yin and Yang Bureau, so it is not allowed to enter the position, otherwise there will be a contradiction between the orientation of immortality and the direction of rotation, so it can only be used as a downward position, so the overall situation does not need to be played. Moreover, there is a downward direction in feng shui.
