What do you mean by dumping wood in the soil?

Lung belongs to gold, liver belongs to wood, spleen belongs to soil … Jin Kemu, Muketu …

If the liver is too strong, it will attack the lung, and if the lung is injured, it will cough. At the same time, the liver wood is too strong, which will also take advantage of the spleen soil, leading to injury of the spleen soil …

"If you know the disease of the liver, you must first strengthen the spleen", so "the wood is leaking in the soil".
