What is the origin of Wuxi Sanfengqiao sauce ribs?

Wuxi Sanfengqiao sauce spareribs have been published for more than 40 years/kloc-0. There is a beautiful legend about the origin of sauce spareribs.

At that time, Jigong came to Wuxi all the way. Because people don't know that this ragged and crazy monk is Jigong, few people are willing to give him charity. Jigong made alms all the way to the front of a cooked meat restaurant and asked the boss for money. The boss opened the door and said he had no money, so he gave him a piece of meat. Jigong asked the boss for it, and the boss gave him another piece. After eating it, Jigong asked for it. The boss said unhappily, "I've given you all the meat. What shall I sell tomorrow?" "Then sell meat and bones!" Jigong took over the topic and spoke slowly, tearing off some cattail stems from the broken cattail fan he carried with him and giving them to the boss: "Put these cattail stems in a meat and bone pot and stew them together. I will eat more meat in the future. " The boss listened to this with a grain of salt, but he gave it a try. After the cattail stems were put into the pot, the meat and bones really became fragrant, and the whole ancient city of Wuxi could smell the aroma. Since then, this cooked butcher shop has started to operate the meat and bone business. With the passage of time, this method gradually spread among the people, and finally formed a famous specialty of Wuxi-meat bone, which is what we call Wuxi sauce ribs today.
