Provenance: From the collection of Mr. William Wu, San Francisco, USA. William Wu (1939-2007) was born in Shanghai and moved to Hong Kong with his family when he was young. In 1957, he was admitted to the Department of Philosophy at Princeton University. Because of his interest in history, in 1979 he received a doctorate in art history from Princeton University focusing on the Chinese artist Gong Xian. After graduation, he was successively employed as a professor of art history at Dartmouth, Oberlin, and other colleges. He later settled in San Francisco, California, where he presided over the Chinese Cultural Center, held regular cultural exhibitions, and devoted himself to introducing Chinese culture and artists to Western audiences. During the 1980s, he traveled between San Francisco and Shanghai and became an important bridge for cultural and artistic exchanges. Professor William Wu and the famous movie star Jet Li are distant relatives, and he was a great help in the early years of Jet Li's career development. Mr. Wu maintained contact with Jet Li throughout his life.来源：來自加州舊金山吳定一先生舊藏。吳定一（1939-2007）出生於上海，年輕時隨家人移居香港。1957年，他被普林斯頓大學哲學系錄取。出於對歷史的興趣，他於1979年獲得了普林斯頓大學藝術史博士學位，主要研究中國藝術家龔賢。畢業後，他先後在達特茅斯，奧伯林和其他學校任藝術史教授。後他定居加州舊金山，並主持了中國文化中心，定期舉辦文化展覽，並致力於向西方觀眾介紹中國文化和藝術家。在1980年代，他在舊金山和上海之間旅行，成為文化和藝術交流的重要橋樑。吳定一教授和著名電影明星李連傑是遠親，在李連傑職業生涯的早期，他提供了很大的幫助。吳先生終生與李連傑保持聯繫。
