Caidie is a loyal maidservant who formerly served Song Tang. She was sold to the third branch of the Zhang family as a maidservant after being driven out of the mansion. There, she suffered abuse, heavy labor, and starvation from other servants who bullied her because she came from the Song mansion. After four years, she is bought back by Song Tang at Mistress He's agreement. Caidie is thin, grimy, and emotionally grateful, kowtowing to Song Tang and vowing her loyalty. She is naturally clever and understands Song Tang's warnings about Qiuling.
