Yanjiao Xianghe Gu 'an Zhuozhou Langfang which is closest to Beijing?

It is more than 20 kilometers away from Yanjiao city, about 50 kilometers away from Xianghe Zhuozhou and more than 60 kilometers away from Gu 'an. Yanjiao bus is also convenient, but there are many people. In fact, there are several places far away from the high-speed bus. The weather is bad, and it is hard to say whether there is traffic jam or cancellation. I remember there was a heavy fog in Beijing last year. The 938 express train that got on at 6: 30 in Xianghe went to Guomao, which was about 165438.
