About 1 hour for 25 minutes. According to Baidu map query, it takes about 1 05km to drive from Dandong to Kuandian, starting from Xinda Line and passing through Heda Expressway and Huangyishan Road, with a total time of about1hour and 25 minutes. Because Kuandian's location is relatively partial, so I can only drive there, and there is no other travel plan.
