Uncle Xiang took Lao Shimo and opened a new tofu shop called "Ruishengxiang", adhering to the craftsmanship of handmade tofu. He has an unwritten rule: good stories with fireworks can be exchanged for tofu and soy milk. Over the years, he has guarded the shop and its rules, listened to the stories of customers, and also guarded the warmth and time in the alley.
