The combined flesh of the spleen is also, its glorious lips are also, and its main liver is also. The kidneys are also the bones, their glorious hair is also, and their main spleen is also. Therefore, if you eat more salty food, your veins will weep and change color; if you eat more bitterness, your skin will be sharp and hairy; if you eat more spicy, your muscles will be anxious and your claws will wither; if you eat more acid, you will be fleshy (moon blade) and your lips will be exposed; if you eat more sweet, your bones will hurt and fall, and the five tastes will also be hurt. Therefore, the heart desires bitterness, the lungs desire bitterness, the liver desires acidity, the spleen desires sweetness, and the kidneys desire saltiness, and the five tastes are also combined. "-Salt (water) sadness (fire), bitterness (fire) lungs (gold), xin (gold) liver (wood), acid (wood) spleen (soil), sweet (soil) kidneys (water), five tastes hurt all according to the five elements.

"——Spring (wood) wins long summer (earth), long summer (soil) wins winter (water), winter (water) wins summer (fire), summer (fire) wins autumn (gold), autumn (gold) wins spring (wood), and the four hours follow the five elements of reciprocity.
