The original text is from "Rhyme in Yangqiu" [Song Dynasty] Ge Lifang, Volume 18:
Jiang Tangzuo, a scholar in Qiongzhou, loved it very much, and gave it a poem saying, "When the sea broke, the white robe ended up together for the first time." And told him: "I will be admitted to the department one day, so I should write this article for my son." And Tang Zuo planned to go to Guangzhou, crossed Ruyang, and saw the son, when Dongpo was already dead. Zi Yu is full of clouds: "there are different ways to grow the grass, and the ancient ginger is under the wind." Adapted from the Jade Dragon Cave in Qiong 'an, show off the Yangcheng calligraphy field. Has the sea ever been broken, and the white robe has been closed for the first time? He saw thousands of people every day, and he believed that Dongpo had a long eye. "
Translation (translated by myself):
Jiang Tangzuo, a scholar from Hainan, (Su) Dongpo loved him very much and gave him a poem: "When the sea broke, the white robe ended up together for the first time." And told him, "I should write this poem for you when you take the exam in the future." By the time (Jiang) Tang Zuo's plan to go to Guangzhou was realized, he passed Ruyang and met (Su Dongpo's younger brother) Zi You. At this time, Dongpo had died. Because of Dongpo's promise, Zi You wrote this poem for Jiang Tangzuo: "There are different ways to grow the grass, and the ancient ginger grows under the wind." Adapted from the Jade Dragon Cave in Qiong 'an, show off the Yangcheng calligraphy field. Has the sea ever been broken, and the white robe has been closed for the first time? He saw thousands of people every day, and he believed that Dongpo had a long eye. "
Jiang Tang was the first scholar in Hainan Island, Zuo Wei. Hainan Island, isolated overseas, was a wild place at that time, and its culture and education were extremely backward. Su Dongpo has the ability to know people, and he foresees that Jiang Tangzuo will be a talented high school in the future.
Now, the online vernacular version of "Su Dongpo and Jiang Tangzuo's Story" is fabricated by modern people, which is not credible.
