According to legend, Fu Cha, the monarch of the State of Wu, was a good gourmet. He likes eating pig's head best, so it is necessary for pig's head to "honor" Fucha first.

Cooked pig's head has a cloud pattern, and the meat color is orange, yellow and black, which is more delicious after freezing in brine soup.

Later, there was a "pig's head cake" in the place where the descendants of the King of Wu lived.
