First, the price is cheap. You can go to all the small scenic spots by buying a pass. Secondly, to remember history from this scenic spot is of great educational significance. To remember the humiliated history of the Chinese nation can better love the hard-won peace. Thirdly, the scenery is beautiful and the scenic spots are super large. Rockery, lake, ancient architecture and Western architecture, lotus leaf and vegetation are interesting to each other. To say something unsatisfactory, it's too big. For those of us who don't follow the group, there is no sightseeing car. Maybe it's true, but we haven't found it. We left one third in an afternoon. In addition, it is good to have fewer people in some places, but there are too many people in some places, which affects the experience.
