Pailong point is made of dragons, because there are too few dragon points. Without using the dragon cave, the water will be washed away. At present, it is generally based on mountains and water, and there should be shelter around it (large shape). If cypress trees are not generally used to solve the problem, the terrain ahead is better. At the same time, there is no perfect yin point, and neither is the emperor's.
Extension: What is the first Yi Long?
In geomantic omen, entering the first dragon refers to the distance from Parent Mountain to Cave Star. First, you need to be fat and live a full life, which is the real dragon of wealth.
The farther the mountain (Long Mai) goes, the longer it will be blessed; Long Mai fell short and soon became fat and expensive.
