According to legend, during the Jiayou period of the Northern Song Dynasty, there was a gifted scholar in Hongzhou who invited friends to travel. When he arrived at a beautiful place, he ordered his servant to cook fish, chicken and meat on the spot and play until the sun went down. However, everyone still wants to meet again tomorrow. When he left, the servant put the remaining chicken, fish and seasoning into a crock, filled it with clear spring, sealed it with a lid, and stuffed it into an unlit ash furnace, sealed it with earth, leaving only one hole for ventilation. The next day, everyone arrived as scheduled, and the servant moved the buried crock out before opening the crock lid. Delicious and delicious! From then on, everyone went out to play like this, and was later learned by a shopkeeper and introduced to the restaurant. From then on, crock simmer soup became famous among the people and became a must for Gancai.
