Everyday, we place some food into fridges. Actually, different food have different ways for storing. If you want to store tea with a fridge, seal it up with a container and place it in a cooling chamber.
It's better to keep the temperature around 5 centigrade and the tea will be kept in good state. As for fruit and vegetables, you can put them stand up-right in a fridge so that they can keep fresh. Except from fridges, some fresh food can be stored elsewhere. To keep fresh milk, you can add a little salt into it, boil it and put it in shade places. Boil it again before drinking. In this way, milk can be kept well for several days.
