Also known as Princess Fukang Zhao Huirou or Eldest Sister. She is Zhao Xin's elder sister, described as beautiful as if carved from jade. She is a genuine child who sometimes shows jealousy toward Zhao Xin but has never bullied him openly or uttered harsh words to him. She often watches the servants attending him, fearing they might neglect him due to his reputation for being dim-witted. She felt a bad premonition when she saw Zhao Xin's smile after his Rejection Reaction ended.
