Qinghe Fruit Shop, which Lin Wanqing has painstakingly run for five years, was privately handed over by her father to her cousin Lin Hao to take over. Facing the replaced payment QR codes, embezzled petty cash, and huge inventory caused by chaotic purchasing, she stood firm on the shop's ownership rights and cleared up membership after-sales disputes. Lin Hao opened another fruit shop to start a price war, setting off peer competition. Under the dual pressure of kinship coercion and commercial risks, Lin Wanqing drew a clear boundary between human favors and operations, stabilized her business through transparent management, and the two ushered in a fair competition for the same large gift box order.
