The Mid-Autumn Festival was coming soon. Ma Laoshi was giving a lecture on Chinese festivals at school. Both Dawei and Han Jiang were interested in going listen. During the lecture, Ma Laoshi brought some moon cakes for the students to taste. Dawei saw a flying woman printed on the box of moon cakes, which aroused his great curiousity. Actually, it came from the well-known ancient Chinese story, ”Chang’E Flying to the Moon ”.
