(A) refrigerator preservation
Put the tea in a dry, sealable container and place it in the fridge freezer. If the tea leaves are small in quantity and dry, they can also be sealed directly in a second-layer moisture-proof film bag and placed in a refrigerator for storage.
(B) metal cans storage
The tea is packed into tinplate teapots with double lids. It is best to fill them with no gaps so that the air in the jars is relatively small and the tea is not easily degraded. Keep in mind that the double cover must be tightly closed, and use a tape to seal the gap in the lid. Put the tea pot in a two-layer nylon bag and seal the bag.
