Yes, it can cure stomach trouble. Two ounces of fresh Chinese olive (100g) and half a catty of pork belly. Wash the olive, wash the pork belly and cut into strips. Then add the stone olive and the pork belly together, add a certain amount of water and salt, and stew together without monosodium glutamate. Just follow the usual habit of stewing soup. Eat pork belly in soup instead of stone olives, and throw them away two hours after meals every night. You have to eat for another ten days. Don't stop. You must remember to eat every day. This is delicious and can be eaten by the whole family. You can eat it whether you are sick or not. If it is not enough, add it. Olive can not only cure stomach trouble, but also cure headache, dizziness, rheumatic joint pain, toothache and so on.
