As the saying goes, "Toona sinensis crosses the house, it will definitely damage the owner". Is this sentence reasonable?

I don't think it's easy to judge this directly.

I haven't heard of this sentence before. I don't know if you have heard of it. At first glance, it will feel a bit like superstition. It doesn't make sense to associate Toona sinensis with people's life and death, but after all, everyone has their own ideas, so I can only say my own views on this.

In fact, it's just a kind of life experience to prevent Toona sinensis trees from growing high in the countryside, because the Toona sinensis leaves that people eat are all young leaves, which mostly grow at the top of the tree, and the old leaves below are inedible. Once the Toona sinensis trees grow high, they have to climb the tree to pick them, but the branches of Toona sinensis trees are relatively thin, so people will easily break the trunk and fall off when they climb up, and injuries are inevitable, so people will build branches.

In addition, Toona sinensis wood is also called "the wood to ward off evil spirits". Since it can ward off evil spirits, it naturally protects the family. If the trees grow too high, they will not grow outside the family, so they will also be built.

In fact, it is obviously unrealistic to link the height of a Toona sinensis tree with a person's life safety. However, we can really find that most Chinese Toona trees in rural areas are not particularly tall, and even so, many people still prune Chinese Toona trees every year to prevent them from growing high.

So, to sum up, I still think it is unreasonable to link Toona sinensis with the death of its owner. If so, I'm afraid Toona sinensis will die. Who doesn't cherish his own life? There are various means to protect himself for his own safety.
