From what aspects can we judge whether the feng shui of a cemetery is good or not?

Ask Feng Shui if I can really talk to you. The cemetery with good feng shui has mountains and water. Zhengzhou has a famous cemetery of Shizu Mountain Pagoda, where the geomantic omen is very good. The cemetery is backed by Shizu Mountain, facing Huanglongchi, with Qinglongling on the left, Wohuping on the right and Laoshan Ping in the distance. Surrounded by mountains and rivers, it is recognized by dozens of Feng Shui masters as a treasure trove of "Dragon Cave".
