Lin Xiulan is the owner of a small grocery store on Yongxing Street, living together in mutual reliance with her daughter, Chen Xiaoyu. Her daughter falls in love with and gets engaged to Zhou Mingyuan, the son of a restaurant owner, but the two families develop differences due to differing values. Meanwhile, Lin Xiulan remains consistently gentle and firm, guarding her little shop while accompanying her daughter to learn how to make decisions for herself. In truth, she has quietly owned one hundred and several dozen commercial storefronts along the entire street for many years without ever drawing attention to herself. As the interactions between the two families and the stories among the neighborhood slowly unfold, the property deeds hidden inside an old iron tin box prompt people to start seeing Lin Xiulan in a new light, while also newly understanding the foundation of confidence she leaves behind for her daughter.
