In the late Northern Song Dynasty, official administration was corrupt, foreign powers frequently disturbed the country, society was in turmoil, and the people were in dire straits. Both of his parents died, and Dou Youde made a living selling tofu. In order to make a living, he left his hometown and went to Doujiaji from Bagong Mountain in Huainan Prefecture, and went to Tokyo to make a living. On the way, he became brothers with Feng Zhong and Feng Xiao, who had evil intentions. Passing by Kanjiaji in Yingzhou, I happened to meet my uncle and aunt, and learned the unique skill of braised vegetables. I also got to know Mai Jinzhong and Mai Baoxing, his father and his son, from Maijiazhuang in Xiangyi. Afterwards, Dou Youde was plotted by the Feng brothers, and all the property he inherited from his aunt and uncle was robbed. He drove a donkey cart to live in a foreign country alone. He fell into a coma due to illness and was rescued by Mai Jinzhong's sister Maisui in Maijiazhuang, Xiangyi. While recuperating, Dou and Mai fell in love and got married. From then on, Dou Youde, Mai Sui and his wife, Mai Jinzhong, Mai Baoxing and others combined Mai's pasta, Dou's tofu, stewed vegetables and other special skills to open workshops and expand their operations. They made a lot of money and became famous in the Central Plains. The exquisite delicacies jointly produced by the Maidou family were selected as tributes and presented to the Tokyo Imperial Palace, and Maijiazhuang was given a new name "Maidou Village" by the imperial court. But unfortunately for the family and the country, the Jin State invaded the Central Plains, Jingkang was humiliated, and the two emperors were taken prisoner. The Central Plains crouched under the power of the Jin State. When the country was ruined and the family was destroyed, Mai Baoxing devoted himself to the army and joined the Yuejia Army to fight on the battlefield. Dou Youde took his son Dou Baowang upstream and went northward. They continued to make a living selling tofu near the Yue family village in Tangyin. His soy products were deeply loved by the Yue family, and they forged a deep friendship with the Yue family. Feng Zhong and Feng Xiao went to Yuejiazhuang to ransack their homes on the orders of Prime Minister Qin Hui. Dou Youde skillfully and skillfully rescued Yue Lei, the second son of the Yue family... After the situation stabilized, the two surnames Maidou returned to Maidou Village one after another.
