The raw materials used to make tangjiu are glutinous rice and early rice, which are generally mixed in the proportion of 4:6, which was passed down from the fishermen's ancestors in Shitang town and is still adopted today. Nowadays, a machine is only used for flour mixing and the rest of the tangjiu making process is conducted by hand.

In Shitang town, tangjiu is regarded as a kind of food, sacrifice, and gift. It is regarded as a return gift when a family's daughters return to celebrate the Spring Festival. Tangjiu is also a good gift for relatives and friends. It is also used when the Spring Festival comes to an end.
