I have been to Lushan several times, Tianma Mountain is the first time to come, I thought it should be a mound, after coming in, I found that there is no cave. A few up and down climbs, it is quite fun, there are several pavilions, there is a leaning tower, although not as good as those beautiful scenery of the famous mountains, but this place in Shanghai is not bad, you can come and climb the mountain in your leisure time
