The Eldest Young Lady of the Shen family is Shen Yunshu's elder sister, who has already married into the Pei family as Old Madam Pei's granddaughter-in-law. She is described as elegant, virtuous, and well-mannered, possessing extensive education and scholarly learning—a stark contrast to her younger sister Third Maiden Shen, who is characterized as utterly uneducated and empty-headed despite her exceptional beauty. Her marriage into the Pei family is significant to the plot, as it creates a familial connection that Shen Yunshu believes will protect Third Sister from potential mistreatment by Pei Huaian. She serves as a benchmark against which Third Sister's suitability as a bride is measured.
