Before I came, I read the Internet and said that the cultural relics in the No. 4 cave in Dunhuang Mogao Grottoes have been relocated as a whole. I took a look and it is indeed worth the money. The cultural relics inside are divided into categories and more detailed. Children also visit more enjoyable, especially at the exit of the museum. There is an interactive area with a stamp. 20 parks buy a 24-open blank book. You can stamp any pattern. There are many children and they are grabbing. I don't know what chapters are covered! Full of a book, the baby is very fulfilling!
