There is no grass in the whole mountain, only one grave is covered with grass. Is it related to Feng Shui?

Grass grows on graves, and offspring thrive. This is a good thing. Grass grows mostly on hillsides and grasslands, which are basically in ventilated places, and cemeteries are generally in such places, so this is no problem. However, this kind of grass grows vigorously and its roots are long, so it needs to be cleaned, otherwise it will cause the cemetery to crack and collapse. If you want to see if there is any problem with Feng Shui, you need to invite someone to conduct on-site investigation.
