I'm in Siping ... I want to go to Changbai Mountain ... Who can tell me the most cost-effective strategy for Changbai Mountain ...

Take the train to Erdaobaihe Town. Check the station on OK Travel Network, which will give you a clear plan. Stop at Erdaobaihe for one night and go up the mountain the next morning. Find your own hotel and bargain with him. Don't listen to anyone's enthusiasm to find you a place to stay. You will get a commission. It's most cost-effective to find it yourself. Last time, we were cheated of some money, but it was a trivial matter.
