As the saying goes: don't plant bamboo in front of the house, and don't plant pomelo behind the house. What is the custom?

There should be no poplars in front, no willows behind, and no ghosts clapping in the courtyard (cypress). This is not a custom, as the Yin and Yang families have said, and so has the gossip about residential feng shui in Zhouyi. Willow is called water vapor and lewdness, so it is often described as a woman's water-based Huayang, willow with a thin waist, and it is also cheap. Ghost clapping is Yin Qizhong, which is usually planted in a cemetery. So people generally don't plant these trees in or around the yard.
