Ying'er is a shop assistant for the Scent of Spring at Chihu Rock, a shop for fine vases. She also makes perfumes as a side job. Ying'er has a romantic personality and a soft voice. She uses a lot of double entendres while speaking, causing the Traveler to mistake the Scent of Spring for a brothel before realizing she was talking about porcelain. She is also an effective teacher as she gives step-by-step instructions to both the Traveler and Timaeus during their respective procedures.
