There is no explanation for your question. If you are a Feng Shui master yourself and you are testing others, then it must be 100% good. If someone else helps you read it, it may not be 100% accurate.
Feng Shui regards Mingtang as the place in front of the acupuncture point. There are differences between the inside and outside of Mingtang. If the mountain is gentle, flat and cave-shaped, surrounded by Longhu Mountain and facing the mountain, it is called the inner hall. Beyond the Neimingtang is the Waimingtang. The middle of the Mingtang is flat and surrounded by mountains. These mountains are Qinglong on the left, White Tiger on the right, and mountains such as Hanmen, Huabiao, and Fubi. There is a curved water in the Mingtang, and the outlet of the water is Shuikou. There are also fields and trees in the Mingtang.
One side of the incoming water is the inlet, which is called Tianmen. The gate of heaven is about to open, and the intention of receiving thousands of waters to go to heaven is coming. When you go to the water outlet, you need to have a sand hand to protect it, but when you go there, you also look back into the acupoint so that the water does not flow straight away. This is a lucky acupoint. Otherwise, it will damage the spirit and Qi, and the acupoint cannot be formed. Going to Shuikou is also called Dihu, which means sand. Households should be closed so that external air can enter the hall and accumulate. If there is water and sand, it will be more auspicious. It will not be easy for the air in the hall to leak out, otherwise the defeat will be rapid.
The water must be locked to protect the things inside the acupoint. So first look for the water outlet. If the mouth of the water is intertwined with the land, there are animal-shaped sand hands (called bird stars) guarding the mouth of the water on both sides. They turn inward and embrace each other. There are Luo stars locking the water. If no water comes out, the prosperity of the game will not be released. The dragon god is not separated, it is a good place to get married. It has nothing to do with spreading. Even if there is dragon energy, it will be released without forming acupuncture points. When looking at the water mouth, first check whether it is close or not. The key to finding the land is here.
