What's the difference between line A and line B of Tianmen Mountain in Zhangjiajie?

AB Two tour routes, the same tickets, the same price, tourists can choose voluntarily. A and B just go up the mountain in different ways, and the tour route is just the opposite, that is to say, Line B and Line A are opposite, and setting different tour routes at scenic spots is actually to divert people. The scenery will get better and better by taking the cable car up the mountain, and there will be a sense of expectation. In the morning, there will be a feeling of fog.
