The hotel owner reserved the luxurious May Day Hall for Zhang Yu, an eight-year regular customer, only to be slapped by Zhang's mother for finding it too expensive and having the booking forcibly canceled. After renting the hall to someone else, business boomed even more, while Zhang Yu's wedding was forced to take place in a farmhouse event tent, where squealing pigs disrupted the ceremony. A year later, Zhang's mother showed up for a baby's one-month celebration, pretending to apologize while secretly setting a trap and recording the conversation. I exposed her scheme. When the pair spread rumors and defamed me, I released the full recording and surveillance footage of the slap. Public opinion turned against them, and the mother and son were condemned across the internet.
