Why come to Shenyang alone? Don't you feel lonely? But I admire you.
There is really nothing interesting near the North Station. When you come to Shenyang, just visit Zhong Street, Taiyuan Street, or take bus 168 to the Expo Park North Station.
If you like Korean culture, you can visit Shenyang West Tower.
If you like movies, you can also visit the Guandong Film and Television City in the scenic area on the chessboard, where many costume movies were shot.
Or go to Tiexi District to see how livable urban areas around the world have transformed from smoky factory areas.
