Chichi is a six-year-old girl who lives with her family on Happiness Road. She is literally happy because of the Happiness Road: she always smells the fragrance of tasty food from the other side of the road. She looks forward to going to school to live a happy life in the future, but she finds the teacher to be very demanding, and she has to speak Mandarin instead of her Taiwanese mother tongue to be a good student in class.
