In the traditional culture of China, pine, bamboo and plum are three old and cold friends. Literati often use them to express their peace and happiness, not worldly, clean and lofty. The first sentence, "When I asked your apprentice, it was under a pine tree", apparently explained that the author could not find a hermit, so he asked the hermit's apprentice about this series of processes; At a deeper level, it implies that the hermit is close to the pine tree and takes the pine tree as his friend, rendering the hermit's high-spirited life. The following three sentences are the boy's answers, including the poet's layers of questioning, with progressive meanings, meaningful words and memorable memories. The first answer: "My teacher", he replied, "I went to collect herbs", from the structure of the whole poem, from the rendering of the environment and atmosphere to the description of the action, from abstract to concrete. In ancient China, there was the idea of pursuing immortality, and the Qin Emperor Hanwu was a typical example. Even alchemists prevailed in the Qin and Han Dynasties, and counterfeiting became a common practice. In contrast, outstanding hermits pay attention to their own cultivation. In seclusion life, enlightenment, health preservation and medication (health medicine) constitute the main contents. This is especially true in Wei, Jin and Israel. Therefore, for hermits, herb picking is an important activity. Its utility lies not only in taking medicine for health, but also in climbing mountains to collect herbs, which is an excellent physical exercise. Therefore, for real hermits, understanding Tao, keeping in good health and collecting herbs are trinity. The profoundness of Tao is manifested in the beauty of cranes, and the communication is like the sky. "My teacher," he replied, "went to collect herbs." This boy showed the typical characteristics of a hermit and added the sadness that the poet hurt him. The second answer is directed at the poet's question about where to collect medicine. This answer is very clear and affirmative, which seems to give the poet some expectations to pursue, but then the third answer seems to guess the poet's expectations, and finally gives a fruitless answer: "How can I tell the difference between crossing so many clouds? "At this time, the mountains are high and the clouds are deep, and the hermit's escape suddenly jumps into the reader's imagination. Around these answers, there are actually two performance structures intertwined and constantly evolving. First, the performance structure of hermit behavior, that is, from virtual to real (not here but in this mountain), from real to virtual (how to say, through all these clouds? ), from the virtual to the real, just like Youlong in the clouds, looming, giving people a sense of confusion, trance, confusion, fully showing the hermit's Shen Feng. First, the poet's own emotional expression structure, from melancholy to expectation (not knowing that he is on this mountain), from expectation to deeper melancholy, reveals an unreachable emotion. The poet was originally a monk, but later he returned to the secular world, but he was not proud of his official career, so he always praised the noble and extraordinary human life. " But on this mountain, how can I tell, through all these clouds? "In fact, it is not only the poet's description of the hermit, but also the realm of life that the poet himself pursues and yearns for.
