On the last day, I went to the Qinghai-Tibet Plateau Natural Museum, and the children of 1.3 didn't ask for tickets. It is recommended to ask a tour guide to explain, 80 yuan, it is still more cost-effective, and there may be no gain in seeing it for yourself. Inside, there are various displays of animals, plants and water sources on the Qinghai-Tibet Plateau, and children are very interested.
