I have a question. I'll be traveling around China for a month, visiting several cities, including Zhangjiajie. From there, we need to travel to Beijing. My question is, is it better to go from Zhangjiajie to Beijing by plane or by train, considering comfort, ease of security checks at the airports, and convenience for a foreigner like myself? Price isn't a concern because I've seen that they cost about the same. I noticed that although the plane takes less time, it is more prone to flight delays or cancellations than the bullet train.
