What does the coffin of Liu Shugen say in Feng Shui?

No matter what kind of tree it is, it belongs to auspicious tree, which is 0/5m away from the grave. The bigger the tree, the better, especially the tree with big leaves, such as mulberry (umbrella-handle tree). If the trees are tall, they will be distinguished in this grave. Mulberry trees can be no more than 15 meters away, so can plane trees, as long as they don't go up. It is forbidden for trees with thorns to grow on graves, such as poplars and trees with thorns and needles in pagodas. If this kind of tree grows on graves and is rooted in coffins or dead bones, then people who are blind or have eye diseases will be blind for generations, and most men will be blind after 30 years old.
