I made an appointment with my friends to take my children to Dinosaur Valley on May Day. I booked tickets online in advance. Although there was a traffic jam on the road and it was noon when we arrived, it did not affect our good mood at all. We had a buffet of 30 yuan in the service area. The dishes were rich and fresh. No queue to buy tickets. It's convenient and fast to go directly to the team window. I saw a lot of dinosaur fossils in Lufeng Dinosaur Hall. It was very shocking! Because the playground is a little crowded for free, we have to queue up for a very happy trip!
