Included in the service center tour, everyone will have a raincoat, watch this 4D movie must wear. The whole screen is round. There are no seats in the viewing area. It's just a big disc. Everyone stands on it. There are fences around it to hold hands. During the broadcast, the disc will sway and rotate up and down with the story, and there will also be water spray, the first time to experience such a 4D movie.
