Zhongtianmen is half the way to Mount Tai. It passes through the ticket office of Wanxianlou from Hongmen scenic spot, which is regarded as a formal climbing. If the physical strength is slightly better for an hour and a half, it will not be a big problem to Zhongtianmen. At Zhongtianmen, you can take a cable car and go directly to Nantianmen. If you don't take the cable car, it will take about an hour and a half to climb up, and it will take more than two and a half time for people with physical deviation. There is a level road in Zhongtianmen. As Mr. Ji Xianlin said, it is three miles of happiness.
