I often hear people say that when choosing a cemetery, you should have mountains and rivers. Is there any significance in this statement?

This is related to Feng Shui. Feng Shui pays attention to the shape of mountains and water potential. Good Feng Shui will bring prosperity to future generations, especially the elderly. When we choose a cemetery, we must take the wishes of the elderly into consideration. Before my grandfather passed away, he specially found the Ancestral Mountain Pagoda Cemetery. According to him, it was a geomantic treasure. You are welcome to accept my answer
