Hi! What's the cheapest way to get to Dalian from qinhuangdao?

Well, the ticket fare of long distance bus is CNY 150 per adult. But there are only one schedule at 10:50 every day from the Long-distance Bus Station and it takes around 7h to arrive. So there is no big big difference between these two transportations.

It's suggested to take high-speed train. It just spend no more than 4 hours on the way.
