Wen Yao's 4-year-old daughter. She is extremely cute, bold, talkative, and has a rich imagination. Her temperament is described as nothing like her mother's—unlike the shy and timid Wen Yao who had a tongue-tie as a child, Xinxin is confident and outspoken. She was admitted to kindergarten through connections and has been signed up for art classes. She has seen a photo of her father shown by Grandma Yu. She loves custard buns and omelet rice.
