Some of these flowers and trees are arranged by position, such as "Parthenocissus tricuspidata on the screen wall, in front of the doors and windows of gold, silver and chrysanthemum"; Some are based on aesthetic taste, such as "peony in front of orchid Guiting, pine, bamboo and plum in front of door are cold-resistant"; There are also psychological needs, such as planting willows, pagodas and dates in front of the door, which are homonyms of "flowing", "pregnant" and "early", meaning that pearls and agates flow into the gate, and gold and silver treasures will give birth to your son early.
The most taboo is to plant mulberry in front of the door, poplar in the yard and willow in the back. As the saying goes, "If you don't plant mulberry before, you won't plant willow after, and there is no ghost clapping in the courtyard."
The so-called "ghost clapping", that is, poplar, is also called "croaking" by the people. When the wind blows, poplar leaves rattle, which makes people upset and easy to be covered up by thieves. Therefore, this kind of tree should not be planted in the yard. Mulberry is similar to "mourning" and is taboo among the people; Willow and "flow" are homophonic, and planting willow behind the house is suspected of money and treasure flowing out.
