Earth-rock mounds protrude from the water jet nozzle. Xu Shanji's "Instructions for the Son of Man: Shafa": "If you are lucky, there are piles of rocks or mud in the Shuikou barrier, which should be between the portals and surrounded by water. The Luoxing legal system must have a great place. " Feng Shui experts believe that Luo Xing, standing by the mouth of water, can stop the surge of vitality, but can gather qi and coagulate points. Therefore, where there are good cities and good places, there must be water stars. "Rocking the Dragon Sutra" says: "Guanlan Mountain is the water mouth, and there must be Luoxing in the water room. There are pillars in the river, where Jiangchuan is born, Li Peng is in front, and Dagu quarries Jinshan as the gateway. There must be Luo Xing to cut off the river so that it does not flow. I don't know how much land has been closed. " As for the towns and villages in various states and counties, there are many Luoxinglei at their estuaries, and Luoxing was born in Pingyang. Because of the land of Pingyang, there are no mountains and rivers at the inlet, such as the lock of Huabiao Town, but it is more expensive to remove water, and there are continents in the water, which repeatedly increases the circulation of water flow. Jiangnan built pavilions or temples, shrines, or Wenchang Pavilion on Luoxing, in order to increase the prestige of its town lock. According to its shape, Luoxing can also be divided into true and false fortune. Correct and delicate, sharp, round, square, flat and straight, respected by the main and senior officials; Broken and burnt, stubborn and fierce, it is a fierce elephant.
