2. It is best for trees to grow behind graves, with mountains behind them. If the tree species are in the rear, it means that future generations will get help from the nobles. If the branches and leaves just cover the grave, just like the corolla, they have the meaning of shade, which is called shade and descendants in Feng Shui.
3. In addition to the orientation and location of planting trees, we should also pay attention to the shape, age and surrounding environment of trees. Just like if you plant a grotesque tree next to the grave, passers-by will inevitably feel a chill when they pass by. It makes people feel creepy, so it's fierce. Another example is that the trees around the grave are full of weeds, which is also unlucky.
