The Calligraphic Art of Yan Fu features more than 100 of his handwritten works, such as copies of calligraphy, letters, annotations, couplets and inscriptions for friends and acquaintances.

"These calligraphic works represent his spiritual treasure," says Shan Jixiang, director of the Palace Museum, at the opening ceremony of the exhibition on Dec 28.

Some exhibits are of Yan's copies of famous calligraphers' works, including the iconic Lanting Xu by Wang Xizhi and pieces from masters like Chu Suiliang and Yan Zhenqing.

Commenting on his works, Zhang Jiazhuang, a professor at Fujian Normal University and a calligraphy critic, says: "His achievements in calligraphy are often overwhelmed by his great reputation as an enlightening thinker.

"His calligraphy style is rooted in Yan Zhenqing's style and also mixed other ancient icons.

"And considering his historical background, his calligraphy looks like an elegant gentleman standing out from a chaotic society. It reveals his strong character."
