Introduction to Qingshiding: Qingshiding is a peak in the upper part of Crocodile Valley, at the intersection of Shenxianwu Valley and Crocodile Valley. There is a steep cliff to the east, and only the north side is passable by pedestrians. The bluestone top is surrounded by green pines and cypresses, blocking out the sky and sun. In the east, you can see the sunrise over the sea of ​​clouds, and in the west, you can see the magnificent scenery of Taipingding, the main peak. According to legend, after Lu Dongbin defeated the crocodile spirit, he sent the herring spirit to guard the crocodile head to prevent it from doing evil again. Over time, the bluefish turned into bluestone, hence the name "Bluestone Top".
