At the end of the Qing Dynasty, Niu Changyuan, a chef in Changyuan, Henan Province, became a famous imperial chef in the palace, and the nine princes loved him very much. Many years later, his son went to Beijing to learn to cook, and he was congenial to Gege of Wangfu. The cow strongly opposed it for a long time, and the father and son turned against each other. In a rage, the son left Niu Changyuan, took Zhang Ziqiang, the famous chef of Taiping Building, as his teacher, and set up a challenge with his father. Niu Changyuan found in the cooking competition with Zhang Ziqiang that the Zhang family's recipe and Niu's family had a lot to integrate with each other. He found Zhang Ziqiang, but he was rejected. After the outbreak of the Anti-Japanese War, Zhang Ziqiang was imprisoned because he would rather die than cook for the Japanese. Before his execution, he secretly entrusted someone to give Niu Changyuan the Zhang family recipe. At this time, Niu lived in seclusion in Changyuan for a long time, devoted himself to studying cooking skills, and finally finished the recipe of "Dachangyuan" and passed it on to future generations.
