Feng shui question: is it good to plant willows in front of the door?

Not so good. The reason why willow attracts shade is that in ancient times, after someone hanged himself, it would float in the air, much like willow branches, so in ancient times, there could be no willow trees around the house. Generally don't build trees in front of the door, otherwise it will block the entry of wealth. Unless there is suffocation in front of the door, such as the hospital or funeral home opposite the door, the Feng Shui master will suggest using proper greening to cover up the suffocation. . .
