This tree has endured the wind and frost for a long time, this tree saves people from danger, this tree is a gift from nature, and it is a good friend of mankind.

Excerpt from the original text: About the tree, my neighbor, Mrs. Kagan, was first told to me. That day, as I was sitting in my backyard watching the October twilight, Mrs. Gagan came to me and asked, "Have you ever seen that tree?" ”

Once, when the father of the famous poet Emily Dickinson happened to see a dazzling Northern Lights over Massachusetts, he immediately ran to the church bell to inform all the citizens. Now, I have this urge to praise this tree. I would like to be a faithful messenger of autumn, so that people in every corner of the idyllic countryside can understand its wonders.

This article is from Robert Caveer's Have You Seen That Tree

Background: Author Robert Keefer tells us that beauty is everywhere through his loving depictions of maple trees. Some people are good at discovering and appreciating beauty, and tell everyone that Mrs. Gagan, Emily, and Dickinson's father are like this, while others ignore the existence of beauty because of their mundane affairs, and the "I" in the text almost misses the opportunity to admire the maple tree because of "a few annoying little things". It can be seen that the key to the natural beauty of Nengxiang's character lies in whether you have a state of mind that can appreciate beauty, and whether you have eyes that are good at discovering beauty, which is the center of this article.

Also known as tulipwood. Its leaves are more than ten centimeters long, different from the leaves of ordinary plants, its apex is truncated, or slightly concave, and there are two deep lobes on both sides, very similar to a horse coat, and like a goose's paw, hence the name. The flowers of the horse coat wood are white on the outside and yellow on the inside, and they are extremely beautiful.

It grows in Guangdong and Fujian in China. It is seven or eight meters high, and all year round, the tree is full of smooth green branches, so it is called a singles tree. Actually, it also has leaves, but they are very small and fall off prematurely, so they don't go unnoticed.

Its branches are fleshy and have white milk. According to analysis, milk contains a very large amount of hydrocarbons and is considered the most promising oil plant abroad. The homeland of the singles tree is in Africa, where the climate is arid, so the leaves are small and shed early to avoid water loss.

5. Poplar. According to the explanation of the character "Yang" in Shuowen Jie Zi, poplar trees grow rapidly and are the earliest trees that can form shade trees, so the right part of the traditional Chinese writing of "Yang" is taken from the traditional Chinese writing of "Yang". Another saying: poplars grow quickly, tall and straight, and the crown has a high-spirited tendency, which is why the poplar tree is named "poplar".

The pronunciation of the word "Yang" is the same as that of the word "Yang", and "Yangshu" is "Yangshu", which indicates a type of tree with a high crown.
