The last part of He Xinlang's Reading History summarizes several times in history.

At the beginning, it was "Apes Say Goodbye to each other", which was about the thrilling moment when human beings were just born. But on the surface, it is so easy to write, as if people and apes just bowed and parted ways. This "Farewell" is very vivid and humorous, but "Ape" is huge, with a profound and distant sense of history. As soon as the two words are matched, they immediately produce poetry, and the reader's heart is shocked at once.

Then there is the long "ignorance era" of mankind, and millions of years have passed. This is the earliest stage of human development-the Stone Age. In the poet's eyes, this era is just a few grinded stones, as if it were just a child's childhood when a person was growing up. The word "grinding" makes people feel long and distant, while "childhood" makes people feel that the poet's grasp of human beings is so atmospheric and kind. This sentence is condescending and there is a sigh of the past.

In the fourth, fifth and sixth sentences, the poet confessed that mankind had entered the bronze age and the iron age from the Stone Age in just three sentences. The phrase "copper iron furnace turns into flame" is both vivid and concentrated. This sentence only writes the symbolic meaning of the bronze light in the flame, and human beings have entered the slave society and feudal society where copper and iron coexist. But it's hard to guess the exact time. It's only a few thousand years. Time flies. In the poet's eyes, time is just a matter of "snapping your fingers". It's not enough. It seems to have passed in a blink of an eye.

The phrase "The world can't laugh" is translated from Du Mu's poem "Climbing the Mountain in Nine Days": "The world can't laugh". However, the poet developed a new idea here (this sentence means that life is less joyful and more sad, that is, more crying and less laughing, more hate and less love), and this sentence injected the meaning of revolution and class struggle, just as the poet pointed out in the article "Abandoning fantasy and preparing for struggle": "Class struggle, some classes won, and some classes were eliminated. This is history, and this is a history of civilization for thousands of years. " In the face of such a fierce struggle, of course, life is hard to laugh. And it's not just "it's hard to laugh"; We must also fight to the death on the battlefield of life. This refers to the specific class struggle between life and death. It means that revolution is a riot, and revolution is "a violent action by one class to overthrow another class." What about the ending? There will naturally be sacrifices and blood. The history of mankind is full of blood and slaughter, and the poet sighs here: "It has flowed all over, and the original blood is in the suburbs." Blood can only arouse the revolutionaries' struggle constantly, and revolutionaries can't laugh in the face of blood.
