Feng Shui! How to distinguish yang trees from yin trees? Is a tree that needs a lot of sunlight called a sun tree?

Generally speaking: trees with fragrant aroma and yang-tonifying properties are called yang trees. Such as pine, cinnamon, etc.; trees that are bitter, cold, sour, and have the properties of nourishing yin and blood are called yin trees. Like plum, loquat, etc. But small individual plants are of little use in Feng Shui. Feng Shui is actually a natural science. The most important thing is the overall environment, which cannot be changed by just one grass, one flower, one tree, Bagua mirror, fish tank, copper bell, etc. Otherwise it would be difficult to find poor people in the world.
