may i ask how to get to inner mongolia from shenyang,pls advise.

Hi, Inner Mongolia is not a city, so you have to make clear that which city of Inner Mongolia are you going? So I can give you the right direction.
Anyway, there are two trains in operation from Shenyang to Huhhot, the capital city of Inner Mongolia. It takes more than 21 h for the whole journey.
Additionally, the direct flight can take you from Shenyang to Huhhot. It only takes about 2 h.
