Introduction to 4D Roller Coaster: There are only three 4D roller coasters in the world. The first one is in the United States, the second one is in Japan, and the third one is in the China Dinosaur Park. The roller coaster project introduced in the Universal Dinosaur City Leisure and Tourism Area combines the characteristics of various roller coasters such as suspended and seated roller coasters. It uses two-wing extended seat cabins. Visitors sit in the seat cabins on both sides of the track and are completely suspended in the air. The warehouse adopts a non-fixed form and can rotate 360 degrees freely while the roller coaster is running up and down on the track, bringing people unprecedented exciting challenges.
