Sui Shou people, an ancient hermit tribe, have guarded the firewood, the fragrance of rice and reunion in the world for generations. After all the elders in the clan retired and disappeared, only Shen Yu and Yan Sui were left. They had been together for thousands of years, with only each other in their eyes. A small lantern-like system "firework" wakes up and tells them to make up for the regrets of those years. So the two of them took the infinite small world "Shanhe Sui" that was complete at the beginning and walked through Changsha in 1933, Zhengyangmen in 1955, Siheyuan in 1965, Military Courtyard in 1968, 2003 By the West Lake in 2000 - solving the cigarette case, providing food during the war, protecting Xu Huizhen growing up, turning the plot in the courtyard into true love, pulling people back from death on the battlefield, accompanying Zhang Qiling, etc. A bronze door. Each world adopts a child, and each world leaves a room of fireworks. There are no monsters to level up, no blood feuds, only three meals a day, four seasons and eight festivals, children around the knees, and old friends reunited. On the New Year's Eve of 2028, the New Year's Eve dinner at Changsuilou will be held, and all the famous dishes will be served at the same table - the longevity will be complete and the fireworks will be endless.
