Siheyuan: Yan Jiecheng's Portable Supermarket

A modern young man transmigrates into a book as Yan Jiecheng, the eldest son of the Yan family in a Siheyuan, and awakens a portable supermarket space. Its inventory is limited, and although it can keep things fresh, it cannot store living beings. In the resource-strapped 1970s, scraping by on odd jobs is difficult, so he brings tea to visit Director Wang at the neighborhood office and ask for steady work. He must keep his secret space hidden, raise his two younger brothers, and deal with his miserly father, all while finding a way forward within the constraints of the times.
