I recommend the following scheme to you? ：

Taking the train saves money, with short journey and short time.

1, the best departure time165438+1October 17. 17 started from Dongguan 16, and 18 arrived in Jinan at 3: 26. Take the bullet train from Jinan at 4: 39, arrive in Cangzhou at 5: 38 in the evening, and then stay for one night.

2,165438+1October 19 can be in Yanshan county in the morning. The route is as follows:

Dongguan-> Jinan-> Cangzhou (the cheapest way to travel)-> Houboji Village, Qingyun Town, Yanshan County,

Then you can go to Beijing by train in Cangzhou to visit your comrades in Beijing. There are many trips to Beijing South Station and Beijing Station every day.

There is no through train from Beijing to Pingliang, Gansu. You need to transfer at Lanzhou Railway Station. There is a train from Lanzhou to Pingliang.

Please see the picture for the specific number of trains.

When you get to Yanshan county, just call your comrades and tell you how to get to the village ~!

I hope I can help you. If you are satisfied, please accept the answer! ~
