Making Dumpling Conserve Better When I make Chinese or Japanese style dumplings I often make too many and then store some for the next day

When I reheat them, they always go a bit strange and seem to taste worse then when they were fresh

Are there ways to store or re-heat the old dumplings to make them conserve better?
Dumplings should freeze very well.  If you freeze the uncooked dumplings immediately and then cook longer the next day, you should have a similar result to your freshly assembled dumplings.
