Up and down, up and down
Kang-kang and his mother brush their teeth.
¡°After we brush our teeth, let¡¯s go to the park.¡±
After listening to his mother, Kang-kang excitedly
brushes his teeth.
Mom says up and down, up and down and Kangkang
also follows his mother saying, up and down,
up and down.
Today is the excited day of going on a family
picnic.
