1. Prepare ingredients: half chicken, 100 grams of chestnuts, appropriate amount of salt, appropriate amount of green onion, small amount of ginger, appropriate amount of water.

3. Then cut the chicken you just prepared into pieces with a knife.

4. Peel off the skin of chestnuts and rinse them clean.

5. Put an appropriate amount of water into the pot and bring it to a boil. Pour the chicken into the pot, add cooking wine, scallions, and ginger slices, cook for about five minutes, and skim off the foam inside.

6. Pour all the materials into the pot, and then add an appropriate amount of water. The water should cover all the materials. After boiling the water over high heat, turn to medium-low heat and simmer slowly.
