I am studying in Xi 'an, and I want to spend my summer vacation in Beidaihe. I don't know the route, but I have to ask someone who knows.

You can take the K 125 train from Xi 'an to Changchun, get off at Qinhuangdao and take the No.34 bus to Beidaihe in front of the station. The fare is 2 yuan (take a taxi to 40 yuan). For students, it is suggested to get off at Liu Zhuang and stay in a private hotel, with a price not exceeding 100 yuan, and a standard room.
