He experienced countless hardships, twists and turns, and disasters, and even faced the destruction of his family. But he never gave in. He believed that evil could not prevail over justice, and that the day of prosperity would come sooner or later. He used the unique tenacity and stubbornness of the old street to protect the national treasure and the dignity of Niujie. At the same time, whether it is Peking Opera actors Yang Shangde (played by Li Jinrong), Li Lianzhang (played by Xin Yi); Ding Guangyuan who pulls camels, Ma Deshan who sells barbecue, or antique dealer Jin Zhaoji, Man Wenkui in the mosque, especially the woman Huang Hexiang. Facing one national disaster after another, they are all the virtues of art; the way of doing business; the foundation of being a person. It shows the unique historical and cultural heritage of Niujie, which has been around for thousands of years. Ding Yulan, a Communist Party member who walked out of Lao Street, eventually returned to Lao Street. She brought expectations and hopes for the future to the people of Lao Street and lit a bright light for Lao Street before dawn.
