Yan Zhenqing's copybook in his later years.

Self-reproach Post, Yanjiamiao Monument and Yanbei are all representative works of his later years.

The biography of Self-reproach Post was written on August 28th, the first year of Jianzhong (780). Regular script, paper book, an essay, 33 lines, 255 words. There is an ink book in Nakamura Sakura Museum in Japan.

This article, also known as "The Book from Prince Shao Shi", was written by Yan Zhenqing, followed by Cai Xiang, Mi Youren and Dong Qichang. Cai Postscript: "When Duke Lu was dying, Zhong Xian couldn't meet each other. Cai Xiang in Puyang fasted until 2002123 October. " Afterword of Mi: "Right Yan Zhenqing sues himself. On April 7, the ninth year of Shaoxing, Minister Mi Youren deliberated and passed. " It was collected by Han Zhou, Jia Sidao, Fengxi, Han Ming, Qingbiao, Anqi, and Qing Neifu in Liang Qing, and later presented to Prince Gong. There are Shaoxing Seal, Neiting Secretary Seal, Angel Seal, Qianlong Yulan Seal and Prince Gong Seal for collection. In front of the post, there are the words "Tang Yan's true feelings". Following the postscript of Cai and Mi, Dong Qichang wrote: "Officials tell the world that there are many books handed down from generation to generation, but there are few books written like Yan Pingyuan in the Tang Dynasty. The plain is very strange, and few people wandered around in ancient times. Since both Mi and Cai appreciate it, Yu Yurong praised it. Dong Qichang. " This post has been recorded, such as "The Story of the Clouds" and "Qinghe Painting and Calligraphy Boat". The rubbings of Loyalty Hall just carved by Liu Yuan in the Southern Song Dynasty are the early versions, and later generations also made a lot of money by collecting posts and engravings. Because Confessions has been circulated and recorded, and passed down from generation to generation, and recorded in some ancient books and paintings, it has always been regarded as Yan Zhenqing's original works. However, after textual research, Cao Baolin and Zhu Guantian think this post is not original today. Qi Gong thinks that "self-criticism is difficult to understand" (note 49 of One Hundred Poems on Qi Gong). ?

The "Yanjia Temple Monument" was established in July 780 (the first year of Tang Jianzhong), and the monument was stored in Anbeilin. The monument is engraved on all sides, with 24 lines and 47 words. There are 6 lines and 52 words on the same side of the plaque. The seal script of Yan's Temple Monument was written by Li. It was established by Yan Zhenqing for his father Yan Weizhen to record the family lineage. Yan Jia Temple Monument was written by Yan Zhenqing at the age of 72. At the beginning of Sui Dynasty, most of the regular scripts in Tang Dynasty were long with fingers, and the words were tight on the left and comfortable on the right. Yan Shu, on the other hand, strengthened the function of wrist force and skillfully used the hidden front and hidden middle to form the effect of penetrating the paper back. It is light and heavy, and it looks very three-dimensional. Yan Zhenqing's main book is horizontal and vertical, and the left and right vertical pens are slightly bent inward, which not only creates a sense of solemnity, but also makes the whole structure round and powerful. These are all innovations that break through the old pattern. Yan Jia Temple Monument is a typical "strict style" work, and it is also the last masterpiece of Yan Zhenqing's tablet inscription handed down from generation to generation. In the third line of the Song Dynasty rubbings, the word "Si" is intact and its extension has been gouged out.

The full name of this monument is "Tombstone, the secretary of the Tang Dynasty and the military guardian in the history of Governor Lang Kuizhou". Yan is Yan Zhenqing's great grandfather. Yan Zhenqing was 7 1 year old when he wrote and published this monument.
