Abstract: The styles of autographs by ZHANG Daqian are characterized with reservation of tradition as well as his own creation. And they are special in appellation and honorifics. There are obvious differences of tittles and honorifics between the works donated to common people and those to people who were in close relationship with him. The study of his autograph styles can help to see the relationship between ZHANG and the donated and identify ZHANG’s calligraphic and painting works.
