Four A or five A did not pay attention, but it was free, which was really good. I have been to Xi'an five times, because it is too big. As a foreigner, I like the atmosphere of Xi'an. Such a good scenic spot, free! Spring, summer, autumn and winter, as long as the weather is good, it's really good to come here and slip away. Rowing or something would be better. And there are fewer people, that is, more people during the Spring Festival, but they are much better than other scenic spots. It's highly recommended. Enjoy the scenery here, if you come here with a heart to see a scenic spot like the terracotta warriors and horses, you may not get much. Now there are some lectures on knowledge that are well done, such as monk's free life activities, large-scale sculptures and so on, as well as large playgrounds for children to play. There is also the Seoul Wall site, I hope the site can be well protected, do not take a long time to weathering. It's suitable for foreigners to visit Xi'an in depth, but not for tourists who visit Xi'an two days a day.
