From Qinghuangdao Train Station to Shanhaiguan Pass

Hi :) I'm travelling from Beijing to Shanhaiguan Pass in the next two weeks. I searched for a train ticket to go there from Beijing and can't find any available one. So I decided to get off at Qinghuangdao Station instead and take a bus from there to Shanhaiguan Pass.

Could you please give me how to get to the QHD Train Station to Shanhaiguan Pass in detail including the time it takes? (Like how to get from QHD Train Station to a bus station in the city, which bus to take, and what stop I need to get off).

Thank you so so much :)
