In July 2008, Shanxi Jinbaozhai Auction Co., Ltd. auctioned a pair of calligraphy couplets inscribed by Liu in Taiyuan. "There are fish in the book, and the door is lofty." Liu likes to collect ancient books, calligraphy and paintings and epigraphy. There is a library in Nangao Village, with a rich collection of books, Zhongding Yi wares and celebrity calligraphy and painting. He once wrote The Story of the Stone, but unfortunately it has been lost. Liu's calligraphy was written by Yan (Yan Zhenqing) first, then Chu (Chu Suiliang), the monument of "Shanxi University Hall" and the "Charity" plaque of Nangao's former residence.
