According to legend, in the early Ming Dynasty, there was a famine in the local area, Shi Ding moved his family, and Ding Gong died on the way. His wife, Shi Li, took her son to the imperial city and opened a snack bar in Xiguan, making a living by selling millet porridge and baked wheat cakes. A few years later, she married her son's wife. Mr. and Mrs. Shi Ding accumulate virtue and do good deeds to help the poor. One day, two officers escorted a Jianghu thief who killed the rich and helped the poor from Changyi to Dengzhou, passing by a snack bar for dinner. Your honor asked for a table and drinks. Mr. and Mrs. Shi Ding sympathized with the thief and sent him biscuits and pickles, saying, "This is free for you. Eat it." After dinner, the thief wants to go to the toilet. Adults see the toilet in the backyard, close to it, and the courtyard wall is quite high, so the shopkeeper leads the thief. When he came to the backyard, the thief whispered to the shopkeeper, "There is a small forest in the west of the city, and there is a grave beside the willow forest. There is something buried between the grave and the tree. Please take it! " Subsequently, the officer escorted the thief to the Huangxian yamen to exchange letters and went to Dongzhou Prefecture.

The next day, Mr. and Mrs. Shi Ding found a bag of things where the thief said it was priceless jewels. As soon as they got together, they decided to use these jewels to go to the government to save the thief. They first went to Huangxian yamen to inquire about the thief's name, and then went to the state capital. At this point, the thief has been sentenced to death and is ready to ask for guilt in the autumn. Mr. and Mrs. Shi Ding spent all their jewels and finally rescued the thief. The thief was puzzled. How did he get released?

The thief is from Weifang. On his way home, he passed the Imperial City and went to the snack bar of Mr. and Mrs. Shi Ding. When he learned the news of the rescue, he quickly knelt down and kowtowed. A few days later, he went back to the snack bar and said to the couple, "Boss Ding, don't open a snack bar. Cotton in Changyi is very cheap. If you traffic in cotton, you will be rich! " Mr. and Mrs. Shi Ding said that the road was not peaceful. The thief took out his whip and handed it to Mr. and Mrs. Shi Ding: "If you hold the whip, all thieves in this area will know, and you will be safe.

"Shi Ding couple sold their property, bought a donkey and went to Changyi in the west to sell cotton. On their way back, they were stopped by a group of robbers. Mr. and Mrs. Shi Ding took out their whips, and the robbers knelt down and begged for mercy. The robbers escorted them all the way back to Huangxian. From then on, Mr. and Mrs. Shi Ding sold cotton unimpeded, and their business grew bigger and bigger, making a fortune.
