Don't keep the whole wax gourd with plastic wrap. Its skin itself is a good protective film. Put it in a dark and dry place. If it is cut, cut the melon and wait a moment. There will be bits of mucus on the cut surface. Then take a piece of clean white paper with the same size as the cut surface and lay it flat on it, and then smooth it by hand. It will remain fresh after storage for 3 to 5 days. If you use non-toxic and clean plastic film, the storage time will be longer.
