Every tree is different. In addition, the choice of trees is also particular. Each tree has its own different representative meaning. For example, Toona sinensis stands for longevity. In some places, the custom of letting children "touch Chinese toon" is still popular, which means healthy growth. Sophora japonica stands for "Lu", while peach, willow and cypress are used to ward off evil spirits. In other rural areas with conservative folk customs, trees are still planted to promote the prosperity of the whole village, mostly evergreen trees such as camphor, pine, cypress and Phoebe bournei, which means prosperity.
The practical application of tree planting traffic in Hong Kong Governor's Office once had an example of changing the fortune of its residence by planting trees. Some geometricians once thought that planting large plants and arranging round decorations in the Governor's Mansion would help to relieve the sense of suffocation, and suggested adding a fish pond. Because the Governor's Mansion was blocked by nearby high-rise buildings, there was no water, so a fish pond was put in the northeast to absorb the water vapor.
