Su was born in 1094 in Bianjing (present-day
Kaifeng,
Henan). He was employed by the Northern Song court's Academy of Painting "solely for his skills at painting", and subsequently designated as a "Painter-in-Attendance" by
Emperor Huizong. He was known for his figure paintings, especially those of women and children. In Su's seminal
baizi () or "hundred-boys" paintings, "generic but appealing" children are usually depicted in gardens, and can be seen engaging in various leisurely activities, from dancing to kite-flying. Su also painted
Buddhist and
Taoist figures, although most of these paintings are now considered lost. Su spent most of his career in
Zhejiang. He died in 1172. ==Legacy==
