Expansion: There is a saying in the countryside that "Toona sinensis will hurt its owner when it passes through the house", which means that Toona sinensis is higher than the roof and may bring disaster to its owner. In this regard, some friends may have realized that the elderly in rural areas may not want the Toona sinensis trees at home to be higher than the roof.
In fact, why does the height of Toona sinensis bring danger to people? The reason is very direct: friends who like to eat wild vegetables should know that the tender buds of Toona sinensis are edible and have high nutritional value. They were eaten as ingredients in ancient China. For example, Su Shi, an ancient poet, once described the Toona sinensis tree as "fragrant in spring".
Here, in ancient times when materials were scarce, especially in ancient rural areas, the tender buds of Toona sinensis trees were naturally "good things".
The germination of Toona sinensis trees is generally around Tomb-Sweeping Day. We know that there will be a lot of rain during Tomb-Sweeping Day. At this time, the branches of Toona sinensis trees are easily broken. At this time, if the Toona sinensis tree is higher than the roof, the ancients will pick it and it is easy to fall from a height. What China lacked in ancient times was not only materials, but also medical technology. Once you fall, rest is ok, and the wound is infected to death, which is a big deal.
Therefore, in the same strain, because too high a Toona sinensis tree will bring danger to people, there is a saying that "Toona sinensis will hurt its owner if it passes through the house", which is circulated in the countryside of the older generation.
