B The full name of Magu Xiantan is Magu Mountain Xiantan in Nancheng County, Fuzhou in the Tang Dynasty, which is the representative work of Yan Zhenqing's regular script. The monument was erected in the sixth year of the Tang Dynasty (AD 77 1) and was later destroyed by lightning. It has a copy of the original extension. The inscription is vigorous and simple, with strong bone strength, the change of line thickness tends to be gentle, and the strokes are less tortuous. When using a pen, there is a "silkworm head swallow tail" with more strokes. Because of its thick lines, in order to leave blank space in the middle palace of the word and avoid crowding, it has to try its best to spread around, and the extended writing method has been pushed to the extreme. Ma Gu Xian Tan Ji is a classic in the history of Chinese calligraphy and one of the excellent models for us to learn regular script.
C The Monument to Li Yanqin is Yan Zhenqing's masterpiece in his later years, which has completely lost its posture in the early Tang Dynasty. This monument is dignified, broad, smooth, magnificent, with an open skeleton and a square extension. It is very clear in horizontal and vertical thickness, and the brushwork of Fiona Fang's turning point is clear.
