Wet sand can effectively maintain the humidity and freshness of ginger. Ginger is more likely to maintain its natural moisture and texture in a humid environment to prevent it from becoming too dry. In contrast, dry sand may cause ginger to lose water and harden, and the taste and taste may also be affected.

It is suggested that ginger should be placed in wet sand to ensure that the preservation environment is relatively humid to maintain its best taste and quality.
