Later, he served as assistant minister of rites, secretary supervisor and prince guest.

He was broad-minded and uninhibited, and had the reputation of "talking about love". Especially in his later years, he was named "Siming fanatic" and "secretary outside the prison" and returned to China at the age of 86. He was a poet in the early Tang Dynasty and a famous calligrapher. Together with Zhang, Zhang Xu and Bao Rong, they are called "four sons of Wuzhong".

He's poems are famous for quatrains. Besides offering sacrifices to the gods and writing poems, his writing style and lyric style are unique, fresh and natural. Two famous poems, Liu Yong and Hometown Couplet Book, are well-known throughout the ages, and most of them are scattered. Today, they are still recorded in the whole Tang poetry *** 19.

Everyone knows his literary talent, but few people know his calligraphy. What calligraphy lovers can see is his representative cursive script "The Book of Filial Piety". The whole volume flies, in one go. Both the rigorous style of the Tang Dynasty and the graceful style of the Jin Dynasty had a great influence on the calligraphy style of the late Tang Dynasty and the Song Dynasty.
