Fish tea is a special dish typically served during traditional festivals among the Li and Miao ethnic groups in Hainan. Despite its name, it is not related to the tea leaves that people drink daily. The term "fish tea" originates from the local Li dialect. It is made primarily from fresh fish, rice, and yeast through a fermentation process. This signature delicacy is used by the Li people to treat guests and is also a distinctive local specialty with rich regional characteristics.
