It's hot every day in summer, and things go bad easily when left outside. If there is a lot left after eating, it is recommended to reheat it, put it in the refrigerator after cooling, and reheat it when drinking. This is because when we drink, it is easy to get our saliva or produce something bad. After reheating, it is equivalent to sterilization once. After cooling, put it in the refrigerator and freeze it. It is okay to drink it overnight, but don't eat too much. After all, overnight dishes can be eaten for a long time.
