I'll give you a street dance. What is this?

Count the money stalks. This stalk means that in the short video of vibrato, a child's father is filming a video of a child performing street dance. In the video, the child is dancing street dance, and the father is saying that this is the street dance he has learned. With the children's movements, the father is counting how much it is worth, because the street dance in the children's videos is so amazing and funny, and this stalk is imitated by the major video bloggers in Tik Tok.
