The tongue coating of a normal person is generally thin, white and moist, evenly spread on the surface of the tongue, and slightly thicker in the middle and root of the tongue. Thick and white tongue coating is a sign of dampness in the body, which is often called spleen cold. Treatment is mainly to warm the middle and strengthen the spleen, and it is best to treat depression and calm the mind. However, if there are no other physical conditions and only a tongue image, it is impossible to make a comprehensive judgment. You can take Chinese medicine, avoid getting angry, and avoid coldness.

The doctor should drink more water, quit drinking and smoking, and eat less irritating and spicy food.
