What you are talking about should be referring to the Nine Star Sect with Greedy Wolf Jupiter, Giant Saturn, Lucun Saturn, Wenqu Mercury, Lian Zhen Mars, Wuqu Venus, Pojun Venus, Zuo Fu Venus, and You Bi Mercury is the first nine stars, the star among them.
This is just the shape of a star, and is in a different category from a mountain of sand. Sand mountains can be like this. Lucun Mountain can be a true dragon star body or a sand body. In fact, Sunayama should be called Suna Hand. They are the retinue of the true dragon, the legs of the dragon's body, etc. The most direct is to play a protective role.
So Lushan and Shashan are not the same, but they are mountains that can be related.
