"The grass on the Lili Plain dies every year. Wildfires can't burn out, but the spring breeze blows." In this famous poem, Bai Juyi vividly described the short life cycle and strong reproductive power of annual herbs. However, "Xiaocao", which was once the object of Taiwan's singing during the folk song period, showed a different image. However, if you listen to this song in the spirit of Zhu Xi's "Looking at Things to Know", you can find that Xiaocao's "determination to grow taller" in the lyrics is actually a little problem, because, in general, the meaning of "Xiaocao"
The spirit of struggle should be as Bai Juyi said, manifested in "even if life is short, the environment is harsh, and the soil is insufficient, but Special Database still strive to open up territory and seek new living space". Of course, some perennial herbs will try to grow upwards, but if the lignification is not enough, they will eventually not grow tall because the tree shape cannot be maintained. This analysis also somewhat revealed the different survival strategies of "grass" and "wood".
Whereas the primary goal of weeds is to expand their territory, the strategy of trees is to grow upwards so that photons can be captured by the leaves responsible for photosynthesis. In other words, most trees still have to compete with other trees for survival in the woods, so they continue to strive for survival space. Even a tree in the wilderness does not need to compete with other trees, but in order to maintain life, it needs to spread its branches and leaves, so that more leaves have a way to capture photons. As a tree that grew slowly in the "Han Empire", although "Confucianism" was valued and protected by the royal family during Emperor Wu's time, it seemed that in the process of "opening branches and spreading leaves", it faced many Interference from other sects of thought during the Warring States Period.
