Mount Tai's majesty lies in eighteen sets, the magnificence of Mount Tai and its climbing. Mount Tai's eighteen sets are the most dangerous section of Mount Tai's climbing path. There are more than 1600 stone steps, which are one of the main symbols of Mount Tai. Here, the two cliffs are cut like cliffs, and the steep winding road is inlaid in them. From a distance, it looks like the Tianmen ladder. From Kaishan to Longmen is "slow 18", then to Shengxian Square is "not tight, not slow and 18", and to Nantianmen is "tight 18", a total of more than 1630 orders. It's really a difficult passage to climb. It's such a difficult word to think of "picking mountain workers" in primary school textbooks. The next day, after sunrise, I went down the mountain and found that more people came up the hill than I did the night before. I have forgotten the eighteen trays of how to get down the mountain, or I haven't gone through eighteen trays. In short, avoid long vacations.
