The rebel army attacked for nine days and nine nights but could not break the city, so they had to camp outside the city. Zhu Yuanzhang and generals Chang Yuchun, Hu Dahai and others discussed how to break the city. Late one night, General Chang couldn't sleep and was pacing outside his tent. Suddenly, they found that Yuan soldiers escorted a group of civilians to the riverside to carry water secretly, opened the city gate, and the Wanjin gate slowly rose, so they quickly woke up Hu Dahai and the rebel soldiers and rushed to the city gate.

Chang Yuchun was really hungry. While he was devouring the buns, he kept urging: "Soup, buns, soup, buns?" Hu Dahai looked at his comrades, who were sweating and carrying tens of thousands of kilograms of weight on their shoulders, and fed Dunsheng. As a plan, a soldier was ordered to pour vegetable soup into the steamed buns, and then feed the steamed buns into the mouths of his comrades. As Chang Yuchun ate, he felt his throat became moist and his strength doubled. Until the soldiers rushed into the city, he lowered the gate.
