What is the difference between the functions of solid water and deficient water in Feng Shui?

Void water refers to roads, streets or ravines; real water refers to real water in the actual sense, such as rivers, rivers, lakes and seas, etc.

In Feng Shui, "Qi will be dispersed by the wind and stop when it encounters water." "Dragon will follow the water." "Water is not Feng Shui" etc. all prove the importance of water in Feng Shui. True water can give people vitality, prosperity, etc., and is an indispensable thing in people's lives. However, Xu Shui does not have these effects, and some are evil, such as railways, highways, etc., and it cannot make Feng Shui "gather together but not disperse".
