Free visit, with ID card and health code. It is recommended to take the elevator up to the top floor and go down to the next layer. There are many stones, minerals, fossils and other objects. Very spectacular. All kinds of gem minerals are so beautiful, you can see it. The huge dinosaur fossils are too shocking. You must punch in when you come to Taiyuan. Many attractions in Taiyuan are free. Spend less and the attractions are good. Give the highest praise.
