1.On August 24, 2025, when a tourist checked into the intercontinental Sanya Peninsula Resort in Sanya, Hainan, they found that red nematodes were constantly emerging from the drain of the bathtub, creating a terrifying and disgusting scene. After the tourist contacted the hotel, it was not until the next afternoon that someone came to handle the matter. Moreover, the tourist's application for a one-night room rate reduction was rejected by the hotel. Subsequently, the tourist lodged a complaint about this matter with the 12345 hotline.
