1. Roast duck, cut the duck legs, duck meat, and leave the duck rack (I asked the stall owner to separate it for me). The duck rack was cut into small pieces
2. Peel and slice ginger, wash and cut green onion
3. Winter melon peeled and cut into small pieces
4. Pour water into the pot, put the duck rack, green onion, sliced ginger, and bring to a boil
5. Turn to low heat, cover and simmer for 5 minutes, then pour in winter melon
6. Continue to simmer for 15 minutes and add salt. Finally, cook on high heat for 3 minutes and it will be out of the pot
