"Falling red is not heartless, but turning into spring mud is more protective of flowers." Flowers without flowers are not things without feelings. Even if it turns into spring mud, it is willing to cultivate beautiful spring flowers to grow. Not for the unique fragrance, but to protect the flowers. Falling flowers are sentimental and withering, and turning into spring mud also protects flowers.
The philosophy contained in these two poems is that "falling red" seems useless, but from another perspective, it can turn mud into flowers and still has value and function. It contains that everything in the world has two sides. "Useful" and "useless" are not absolute, but relative. The key lies in the observer's perspective and his own value and function.
