Yangguan ruins are really impressive. Free tour guides are provided, and as soon as you enter the ticket gate, a tour guide will come forward to explain when there is a free tour guide. Starting at the point, regardless of the number of people. Although the tour guide is free, the quality of the explanation is not discounted, very serious. On the way to the site of the campfire, there is a "guard general", will give some questions to test tourists, can not answer to be punished. He also works as a task of selling souvenirs. But there is a lot of feelings about Chinese culture, and it is not the commercial atmosphere of the general attraction staff. It is not particularly refundable for goods. It is more enthusiastic to tell you about history. I feel that this kind of business idea is more comfortable. The introduction and dissemination of history and culture are free and priceless. Commercial entertainment activities, such as donkey carts, camel riding, etc. are charged according to the needs of tourists.
