As the saying goes, "Don't plant mulberry before, don't plant willow after", and "ghosts clap their hands" in the yard. The mulberry here refers to mulberry, and the willow refers to willow. Mulberry trees are not planted in front of the hospital because "Mulberry" and "Mourning" are homonyms, and it is unlucky to go out to see Mulberry (Mourning). Not planting willows later is related to the funeral of the deceased. Because both the "mourning staff" and the "evocation flag" are made of willows, willows should be planted behind the grave as "cash cow" and "tomb tree". Therefore, willow trees are also easily considered as funerals. "The other is that willows don't seed. If you plant it behind the house or in the yard, you are afraid of being hurt, and you feel that this family will have no children and descendants. "Clap your hands refers to poplar. When the wind blows, poplar leaves crash like "ghosts clap their hands". It's unlucky to plant poplars in the yard for fear of attracting ghosts. If mulberry is planted first and then willow is planted, the population will be lost, and no children will be left behind. The "executioner" in some places refers to peach trees. Because peach blossoms, peach branches and peaches are blood red, monsters are willing to live on peach trees, so they dare not plant them in the yard. Peach trees can only be planted in the backyard, not in the front yard. It is generally believed that there are evil spirits on peach trees. If planted in the front yard and rooted in the house, people will worry about their lives. It is generally believed that mahogany has magical power, and it is often used as a pillar to ward off evil spirits. Whoever plants a peach tree will be troubled. Some people say that the owner of the peach tree has run away and begged. ?
