Li Yanqin Monument was undoubtedly written by Duke Lu. The style of this monument is really different before and after. Personally, I think the reason is that the tablet is written twice, and the dividing point is at the "seven sons zhaofu". The first part mainly records the life stories of Yan and his elders, with strict statutes and bold style, which is close to Guo Jia Temple Monument. The second half of the pen is more leisurely and free, and the taste is stronger.

It is generally believed that the age of Yan Monument was set by Ouyang Xiu in the Record of Jigu, that is, Yan Zhenqing was 765,438+0 years old in the 14th year of Dali. However, Yan Zhenqing's other inscriptions in his later years are quite different from this one, which should be the main reason why some people think that Yan Bei is a fake. Personally, I think Li Yanqin Monument was written by Yan Zhenqing when he was about 60 years old.

Detailed textual research on the year number of Li Yanqin Monument can refer to Liang Qiu's Textual Research on the Authenticity and Year Number of Li Yanqin Monument and Gui Xuenong's Textual Research on the Year Number of Li Yanqin Monument.
