Hop, Hop, Hop!

The Chinese word for "rabbit" is "tuzi", and when we're reading my animal books, my parents say "Tuzi! Hop, hop hop!" I also like to pull up my shirt and put my finger in my belly button, and my parents say the Chinese word for "belly", which is "duzi". But I have trouble hearing the difference between "tuzi" and "duzi", so now I like to pull up my shirt, put my finger in my belly button, and say "Hop, hop, hop!"
