Qiqi is dancing. What is this?

This is Chick Cha Cha, an English nursery rhyme, Qiqi, Qiqi. Clap your hands, clap your hands, cha-cha. About why this cha-cha dance is on fire, it may be because of ghosts and animals, or it may be because the duration and movements of the whole video are very easy to be imitated, and it is easy to create more funny things in imitation.
