From my view of the five elements of calligraphy, this paper discusses this problem: regular script belongs to soil, soil can resist water, health depends on fire, can resist wood, and belongs to human spleen.
Looking at the living conditions of modern people is more laborious than physical exertion, which is very different from the health care of ancient people. This heart and kidney are losing money and tend to be more violent. Obeying social rules, emotions such as emotions, joys and sorrows cannot be released reasonably, and resentment, anger, joy and hate are hidden in their hearts, which is unfavorable to their spirit. The heart is full of fire and God is strong. Its nature is evil and precious. Burn its wood, smoke its source, destroy its liver, confuse its gold, confuse its behavior and hurt its lungs. Only the soil can benefit from it, so the spleen is thicker. He has a rich temper and plenty of ammunition. He likes to write regular script, but the rest is beyond his power.
The theory of five elements is almost in one place, and it is said too much.
This is a point of view, which is limited to reference and insufficient.
