Zhang Xianzhi: At the end of the article, the way to point out the center and theme in one or two sentences is called "pointing out the theme at the end of the article", and "zhi" refers to the theme and center of the article. "pawn" is the end. Properly used, this technique can increase the profundity, appeal and structural beauty of the article, and has the artistic effect of "making the finishing point". Also known as "observing your own opinions from your own chapters", it is a very common writing method. Generally speaking, it is used in almost all styles, especially prose.
Zhang Xianzhi is one of the ways to conceive. Bai Juyi, an outstanding realistic poet in the Tang Dynasty, said in the preface to the new Yuefu: "The first sentence marks its purpose, and the pawn chapter shows its will." At the end of the article, the author will naturally express his thoughts and ambitions, giving people an inspiring and uplifting force. Fan Zhongyan's Yueyang Tower is a model of this technique.
