The sage and wise master Yang Gong said: "If there is no mountain, the dragon god will not go into the water, and the water dragon god will not go up the mountain." This means that there should be no "mountain" where the prosperous and angry stars are. However, the general Feng Shui masters who do not understand this principle, because they do not know the fortune and stars, will always use the situation of facing the mountains and rivers as the correct method to investigate the prosperity of the Qi of mountains and rivers. If they ask for wealth, they will end up hurting them and losing their wealth. This is fatal. mistake. Those who do not believe can find more tombs and test them, and they will naturally come to the correct conclusion.
