During the National Day Golden Week peak travel season, Lin Wan, the owner of a four-star hotel, reserved 30 south-facing business king rooms for Zhang Hao, a loyal customer of ten years, at 500 yuan per person including accommodation, three meals, scenic spot tickets, round-trip transfers, and tour guide services. However, due to a misunderstanding, Zhang Hao accused Lin Wan of overcharging regulars, shattered their decade-long relationship with a slap, and tried to force Lin Wan to lower her prices by threatening to cancel the rooms. Lin Wan directly booked the 30 rooms to a tour group of a hundred elderly people. Left with nowhere to stay, Zhang Hao and his employees suffered immensely and finally came to deeply appreciate Lin Wan's kindness to old customers, but everything was already too late.
