The Jingguanlou Collection of Chinese Painting and Calligraphy: Zhu Qizhan is a tribute to Dr Leo Wong's generous donation and dedication to share Zhu Qizhan's oeuvre with the public. The catalogue comprises more than 250 priceless works by Zhu, including paintings, calligraphy works, porcelain paintings and purple clay teapots with rubbings, which aims to give a broader picture of the artist’s century-long creative career. It also provides definitive and reliable evidence for the study on Zhu’s aesthetic philosophy and evolving artistic style over different life stages.
