Legend has it that in ancient times, after the Eight Immortals crossed the sea to kill the Dragon King, on their way back to the Fairy Residence, they saw the drums and lanterns in the neighboring village and went down to Xiangyun to join in the fun. It turns out that Mr. Wu, the richest man in the village, married a woman, and it rose at that time. One person cooked a good dish (namely, Cai Helianzi, Xiangzi sea cucumber, a bowl of meat, my uncle's pickled fish, and Dong Bin's big fish)
Soon, Xianju people changed the Eight Immortals table for eating into the Eight Immortals table, and all the eight specialties of the Eight Immortals were used in the wedding banquet and were honored as eight bowls. The specific name of the eight bowls was changed to the above eight bowls.
