Zheng's years in Thailand.

(1324— 1328), Zheng moved to Pingjiang (now Suzhou) and lived in Wuzhong for nearly forty years. During this period, his fame became even higher. Yuan You "never liked writing books" and once said to scholars: "Classics are classics, history is longitude and latitude, and righteousness is the source. Scholars can do what the ancients meant, but dare to discuss it in private! " It shows that he attaches importance to the academic thought of opposing the empty talk about classics and history, which people call insightful (Su Danian's epitaph of Mr. Suichang, Appendix to Overseas Chinese, Wu Ji). Pingjiang, where Lu Zhi is located, is rich in products and has a collection of scholars. Yuan You's "rich voice and good interest don't move his heart, and Zhejiang and Taiwan are arguing to recommend it by virtue, but his arm is unwilling to be an official" (Selected Works of Gu Yuan). Until the seventeenth year of Shun Di (1357), Pingjiang Dao was hired as a professor of Confucianism, and Yuan You left happily, saying: However, he only stayed in this position for one year, and then he died of illness.

Zheng's article is quite famous. "Good writing, with the style of ancient literati, clear and solemn poetry" (Selected Songs of Gu Yuan). At that time, Gu Zhongying, a rich man in Kunshan, neglected friends and built villas, which was called the beauty of Yushan. He took Du Fu's poems and inscribed the place where he studied as Yushan Caotang (Collection of Overseas Chinese Wu 10, Yushan Caotang), and became the winner of the literary meeting of scholars and celebrities from all directions. "Beautiful scenery, gathering of scholars and friends, and the ability of courtiers from all directions are words. Anyone who crosses the Soviet Union will come. " Be happy, be happy, be happy, be happy, be happy, be happy, be happy, be happy, be happy, be happy, be happy, be happy, be happy, be happy, be happy, be happy, be happy, be happy, be happy, be happy, be happy, be happy, be happy. They are all famous for their articles on Confucianism, and their biographies can be found in Yuan History and Ming History. However, Zheng can be called a guest of Yushan Caotang. "Yushan Caotang will host the meeting of literature and wine, and celebrities will gather and push more." There are inscriptions, which are not expensive but expensive "("Selected Songs of Gu Yuan "). The pavilion mentioned here is a kind of style, which refers to imperial edicts and other royal application words written by courtiers such as Hanlin Academy, Jixian Academy and Kuizhangge College. Style and calligraphy strive to be elegant and neat, and both have fixed formats. However, Zheng's inscriptions and calligraphy are superior, and their influence is better than that of pavilion, which is more valued by Soochow scholars. In this respect, Zheng can be called the leader of Soochow scholars. When describing the behavior of the stele owner, some of his words often reflect the social customs and conditions of Wuzhong in the Yuan Dynasty, as well as the author's thoughts and feelings.
