On the fourteenth day of the first lunar month, there has been a custom of eating bad soup in Taizhou, Zhejiang.

The Qing Dynasty's "Taizhou Waishu" records: During the Lantern Festival, meat, vegetables and flour, assorted shepherd's purses and bamboo shoots are used as soup. The more it is, the more expensive it is, which is called eating bad soup.

As time goes by, Taizhou people eat more rich dishes, mainly with mustard greens, shredded pork, pig ears, pig tails, mushrooms, Sichuan bean boards, bean noodles, winter bamboo shoots, fungus, dried tofu, oil pickles, and taro.

Wait for seasonal vegetables, cut into cubes or minced shapes, put them into a pot and cook them together, then add water to the rice noodles and pour them into the pot, and cook until they become a paste.

Because distiller's grains were added to blend in ancient times, it was called "dregs".
