Yonghe leather is commonly known as Yonghe Qianzhang, which is called tofu skin in the north and louver in the south. It is a soy product. Yonghe leather has a long history. It is said that tofu was created by Liu An, the Huainan king of the Han Dynasty. It has been more than two thousand years. In some places in Hong'an County, the custom of "making leather" has been circulated throughout the year, and "Yonghe Pizi" has the most unique flavor. As the Spring Festival approached, the leather workshops in Yongjiahe Town began to flourish again. The thick and tender “Yonghe Leather” became a special dish in the group.
