I watched a trailer in Henan Satellite TV the other day. It's about a couple staying in a hotel, but I was surprised to find many photos in the room. ...

I think it's the Pinhole Hotel. This is a brief introduction of Pinhole Hotel. "David wants to spend the long night with some unlabeled videos he found in his room. From the pictures, these videos seem to be just some cheap horror movies, but after watching them for only a few minutes, David began to feel cold, because the horror and cruel violence in the videos seemed so real. Moreover, David soon noticed that the background in the movie was their room. It turns out that this room is full of hidden cameras, and Mei Sen's so-called "honeymoon package" actually makes them the protagonists of the next horror movie. "
