is a snack. Pipi dried bean curd is actually a snack made of sweet potato powder and dried bean curd, which tastes much better. In addition, personally, I prefer to stew pork ribs soup with sweet potato skin. When the time comes, I will chop the pork ribs into small pieces, and peel off the yam and potatoes and cut them into small pieces. Wash the vegetables and cut them into small pieces, then put them in a pot, sprinkle some condiments and water and cook them.
