How does cf Biochemical Hotel get stuck underground?

The bug in the biochemical hotel is under the floor under two trees on the left and right sides of the bridge. You can insert it according to the normal card method, or you can squat down and press the keyboard to turn your body, but the probability is very small. You can also stick the floor card next to the stairs next to the bar. There is also a board on the gazebo. I think it goes without saying that many people can jump. At present, there is only one BUG in the death playground, that is, one of the four pillars supporting the pirate ship is stuck. The way to get stuck is to follow the post all the time and not move. If you get stuck, you will suddenly squat down, then get stuck and hide under the pirate ship, and no one can catch you (you can try other ways to get stuck in the death playground). If you don't get stuck a few times.
