2. Preservation in fresh-keeping bag: put the lettuce in a clean fresh-keeping bag, and then put it in a cool place at home. Don't bask in the sun. In this way, it can be preserved for about three days. When preserving lettuce, it cannot be stored together with fruit. If stored together, it will affect the freshness of lettuce and speed up the decay of lettuce.
