Hi. We will stay few days in Beijing and few days in Qinhuangdao.

Both cities boast well-preserved wall sections but of different characteristics.
In Beijing, you are suggested to visit Badaling or Mutianyu, which are the most popular sections winding along the mountain ridges.
Or you can also view the unique scene of the Wall joining the sea in Shanhaiguan, Qinhuangdao. You can make your choice according to your personal interest. :)
