Chop the duck, add a little oil to the pan, pour the duck and ginger into the oil pan and fry for about 3 minutes. Add salt, monosodium glutamate, garlic, a little soy sauce, continue to fry for a while, then add 2 spoons of low-alcohol liquor, add water after a little frying, and cover the pot. Bring the fire to a boil and simmer for 30 to 40 minutes until the meat is rotten.
