In addition to the storage time of food, people also need to pay attention to the temperature of the refrigerator. The weather in our country in recent years is often high during Tet holidays. This temperature will have a huge effect on food, creating conditions for bacteria to grow faster. That leads to food that is more perishable even if it is kept in the refrigerator.
