Which expert pointed out: according to what standard does Chinese medicine divide things into yin and yang? For example, if the chicken is positive, it should be stewed with water and the duck should be roasted ... thank you. Chicken belongs to Yang, in heavenly stems and earthly branches. All together, unitary is water. In divinatory symbols, they are divinatory symbols, with Yang in the middle and Yin on both sides. Anyone who has studied traditional Chinese medicine knows that it is called the fire of the dragon thunder, so according to the method of China people, the chicken should be stewed and eaten. Ducks are cold. If you want to roast them with fire, you must eat them when you go to Beijing.
