His collection adheres to the principle of equal emphasis on culture and art, and particularly respects the calligraphy of scholars and literati. He has unique insights into literati calligraphy: "A true literati is of high character and pride, and his ink marks shine with the brilliance of truth, goodness and beauty. This is where the value of literati calligraphy lies." He emphasized the importance of calligraphy in painting and summed up the appreciation experience of "appreciating the calligraphy before reading the painting. If the calligraphy is poor, the painting must be vulgar; learning will enrich the spirit, and high quality will eliminate the dust." He has written "Wu Zhang's Shu Dialect Calligraphy", "Pleasant to the Eye and Pure to the Soul - Collection and Appreciation of Master Hongyi's Calligraphy", "Lu Xun---An Unforgettable Memorial of Chinese Calligraphy in the 20th Century", "Write More, Think More, Read More" ——A Trilogy of Learning Calligraphy" and many other articles were published. His calligraphy works were sold for 92,000 yuan at Beijing Chuanshi Auction.
