The experience was great. There were many exhibition halls and fossils, which the children loved. The museum service was excellent. We bought two children's tickets and one ticket code, but upon arrival, we discovered that children under 1.4 meters were admitted free of charge. After explaining this to the ticket checker, only one ticket was checked, and the phone indicated that a refund could not be initiated for the unchecked ticket. At the ticket window, we explained the situation, and after consulting with the curator, the staff had us register our information. The museum then contacted the platform and quickly processed the refund. After the refund, the museum even called to confirm. Very thoughtful service, thumbs up!
