Regarding wine, there is a dialogue between Huangdi and Qi Bo in Su Wen Jue Lun. Qi Bo said: "When wine enters the stomach, the pulse is full and the menstruation is weak. Spleen governs the stomach to run body fluids, and deficiency of yin leads to inflow of yang, which leads to disharmony between stomach and essence, and essence failure does not affect its limbs. Alcohol and grain gas are competing, and the heat is abundant in the middle, so the heat is everywhere in life and the internal heat is also submerged. The husband is full of wine and strong, the kidney fails, and the yang is full, so the hands and feet are hot. " In other words, wine is the essence of Shui Gu, the liquid of cooked food, and its spirit is fierce. Therefore, after the stomach, people walk on the skin from Wei Qi to fill the veins, and the meridians can't be filled at the same time, so there will be yin deficiency again, and yin deficiency will attack the stomach with Yang Qi.
