Ice cream moon cakes can only be kept for two hours at room temperature. After buying ice cream moon cakes, you must keep them at low temperature when you take them home (Haagen-Dazs has prepared dry ice for customers, and you can still eat fresh moon cakes when you take them home from the store). At the same time, the storage time shall not exceed the marked shelf life. It is best to eat as soon as possible, not for too long, and not to eat too much at once.
