Mo Yujie went shopping and traveled to the Yin Dynasty, becoming a four-year-old girl. Living in the busy city of Taipei, she was accustomed to a fulfilling life from 9 to 5. When she came to ancient times, she didn't want to spend a boring childhood wandering in the yard like other peers. Therefore, she returned to her favorite thing, drawing pictures, to earn extra living expenses. She also met four young people from rich families who had money and leisure, and started an adventurous journey together.
