Takeout delivery driver Li Fugui accidentally travels through time to a Beijing courtyard house in 1958, awakening a portable space containing twenty mu of land and a fishpond. Starting as an apprentice and porter at the supply and marketing cooperative, he relies on scarce supplies like live fish and fresh vegetables produced by his space to figure out the rules, build broad connections, and advance step by step, promoting himself from a handyman to a planned procurement agent. While helping his family manage their livelihood and facilitating his eldest brother's marriage, he gradually develops mutual affection with his blind-date match, Xu Jing. Amidst the tidal wave of tightening supplies, he relies on his spatial advantage and penetrating worldly wisdom to build family wealth and pave networking pathways, firmly taking root in an ordinary era and turning an ordinary life increasingly prosperous and full of promise.
