A bean bag is a pack made of yellow rice (yellow rice or small yolk rice) and covered with soy sand or red beans, which can be eaten after evaporation. It usually appears in northern China. I know this bean bag because he's from the North, and it's very nice to remember that she came to Shanghai from the Northeast, a thousand miles away, and a backpack was full of bean buns.
