Metro direct, convenient transportation. Exchange valid ID cards for free tickets. Notice that the entrance is on the top of the hill. At first we thought it started on the first floor. The climbing process is very tiring, four stories high, not steep along the way, but there are no handrails, can not stop, can only climb up in one breath. Indoor visits are also interesting. Restored dinosaur maps are everywhere. The fossils are very large and the voiced dinosaur calls are vivid.
