2. Record the true history. For example, Du Fu's "Three Officials and Three Farewells" recorded the decline of politics and the sufferings of the people in the middle and late Tang Dynasty. "The wine and meat in Zhumen stink, and the bones on the road freeze to death", "Where the petals are already like tears, where the lonely birds are sad" and "There is no bone by the river, and there is still a dream of living in the boudoir"
3. Elegant social channels. When bidding farewell to relatives and friends, people often fold willows (because willows are homophonic) and write poems to bid farewell. For example, "However, China holds our friendship, and heaven is still our neighbor" and "Peach Blossom Pond is deeper than thousands of feet, not as good as Wang Lun".
4. Poetic. For example, Yue Fei "swears to reward the sage seven feet, and angrily refers to the end of the world without tears." "He is eager to eat meat, and he also talks about his desire for the blood of Huns." Li Bai's "I would like to cut Loulan with a machete"
5. Take poetry as an artistic means to express feelings about beautiful things. For example, "The flowers have not been swept away, but the tourists in Ti Ying are still asleep", "There is nothing in the south of the Yangtze River, I will give you a spring" and "I think Qingshan is so charming that Qingshan should see me".
6. I miss you. For example, Su Shi's "broken intestines are broken every year, and the moonlit night is short"; Another example is Song Zhiyi's "I miss you every day, and I drink Yangtze River water."
7. Speculative analysis is equivalent to the shortest paper. For example, "If the stone overthrew the State of Wu, who will be the vanquished of the State of Yue", "Jiangdong's children are versatile, and it is unknown that they will make a comeback" and "Only make Longcheng fly, don't teach Huma to cross the Yinshan Mountain"
