? In the biography of Su Dongpo, the author Mr. Lin Yutang said that "Su Dongpo often writes the best poems for children". The best example is when Su Shi was in Mizhou, which coincided with the Mid-Autumn Festival. Because I miss my hometown and can't meet my distant family, I wrote Mink Head under the Moon. Later critics thought that after this word was written, other words with the theme of Mid-Autumn Festival could be abandoned. "People have joys and sorrows, and the moon is full of rain or shine. It was difficult to accomplish in ancient times. I hope people will live for a long time, and the last sentence expresses Dongpo's most sincere blessing to his distant brother. " For decades, the two brothers' poetry exchanges have never stopped. Almost everywhere Su Shi went, there were letters and poems to Ziyou, and there were more than 100 poems on Ziyou, such as Ziyou, Bieziyou and Ziyou poems. Today, the mink head has been adapted into a modern play, which is well known to people, and the deep friendship between Su Shi and Ziyou is also well known to the world.
? When Dongpo was arrested and imprisoned for Wutai Poetry, many friends spoke for him, but they were all demoted or punished in the end. In the end, everyone dared not stand up for him for fear of endangering themselves. Ziyou is also implicated, but life is not rich. He resolutely took his brother's family to his home with seven children to help take care of him and deliver food to Dongpo. Regarding the Wutai poetry case and the experience of his brother Su Shi, Zi lobbied "What is Dongpo's crime, just because his name is too high". Yes, the title is too high, which makes other officials jealous. Once someone points the finger at Su Shi, they will attack him.
? On one occasion, on the way, the two brothers spent the night at Huaiyuan post. In the evening, it's stormy and cold. Su Zhe got up and put on his clothes, and saw his younger brother reading a poem by Wei, a poet in the Tang Dynasty. There are two lines in the poem, "I know it's a stormy night, so I can sleep in the bed." The scene in the poem coincides with the scene at the moment, and in an instant, their hearts are moved. So they made an agreement of "writing poems on rainy nights", saying that they would never love officialdom for a long time again, and retire to the mountains early in the future, and then relive the leisure on the "stormy bed", enjoy family happiness and enjoy life. And after that? "Sleeping at night" became a knot between them. It has become a topic repeatedly mentioned in hundreds of poems sung by each other, and it has also become a witness to the deep feelings of the two brothers.
? Mr. Lin Yutang commented on the two brothers, "Zi is calm, practical, reserved and taciturn, and Dongpo is light."
