Han Yu

Suddenly I don't know how to be happy, and I want to take it off for no reason.

Andrew's long wings are like clouds, and I am excited by the wind.

No floating dust, death, sadness, joy, abandonment, right and wrong idle people.

Tang Xianzong, a Buddhist, welcomed the Buddha's bones into the palace, causing a sensation in the capital Chang 'an. In response to this incident, Han Yu wrote an article on the Buddha's bone table, pointing out that believing in Buddhism is not good for the country. The article mentioned that since the Eastern Han Dynasty, emperors who believed in Buddhism were short-lived, which made Tang Xianzong, who was afraid of death, fly into a rage and insisted on putting him to death. Because the ministers begged him, he was saved and exiled to Chaozhou, Guangdong. When Han Yu set out for Chaozhou, he passed Lantian Pass in Lantian County, Shaanxi Province and wrote this poem for his grandnephew Han Xiang.

A letter in the sky, eight thousand in Chaoyang Road at night. If you want to eliminate disasters for the wise, you are willing to decline and cherish the old! Where is the home of Yunheng Qinling? The heavy snow hindered the horse's progress. I know you came here on purpose so that I could collect my bones by the river. ("Moving to the left to show my grandnephew")

Li Bai's poems gushed out in one breath, and so did Han Yu. But Li Bai's mood may be a roar or a sigh. He pays attention to nature. Han Yu, on the whole, makes people feel like singing blackheads, trying their best to shout it out in a loud voice, and what is important is the effect of strangling people. This is called momentum!

Suddenly I don't know how to be happy, and I want to take it off for no reason! Andrew's long wings are like a cloud that gives birth to me, and he will never float dust by the wind! Forget one's life, be sad and happy, and pay for idle people! (Tribal Tiger)

What I'm talking about here is Zhuangzi's philosophical attitude, which equates life with death. In fact, since I'm not happy when I'm alive, I'd rather get rid of it, so I'll say something after all. But the poet just stopped and immediately bounced back, adding, "Andrew's wings are like clouds, giving birth to me, riding the wind to excite Liuhe, and never floating dust", hoping to grow wings as big as clouds and fly out of heaven and earth as Zhuangzi said. This kind of poem, no matter how to downplay the sadness of death, can't get the tone. The poet just sings so tragically that he will never step on other people's footprints to find treasure. He would rather be accused of being grotesque than praised as mediocre.

Appreciate:

One of the characteristics of Han Yu's poetry is to destroy the external form of poetry that has been gradually standardized and orderly, pursue harmonious rhythm and stable sentence patterns, and make it loose and deformed. He often introduces the syntax of prose and parallel prose into poetry, making it long or short, ups and downs and changeable. For example, the tribal tiger adopts the sentence pattern of eleven, six, eleven, seven, three, seven and seven. The first sentence is "Tribal tigers are ignorant of life, and I want to get rid of it for no reason", which is completely syntactic in prose, but it gives people a sigh-like shock from the heart.
