Shu Ping is the eldest sister of Shu Yuan and Shu He. She is married and has given birth to twins - a boy and a girl. She is one of the few people who knows about Shu Yuan's secret child, along with the midwife. Her successful birth of twins is mentioned by Aunt Xie as a positive sign when trying to convince Aunt Zhang to consider Shu Yuan as a bride, suggesting that if Shu Ping can give birth to twins, Shu Yuan can too.
