The stalk of painting North North comes from the lyrics "Baby painting, baby painting" in the song "Happy True giao". Because of the simple and magical melody of the song and Jiao Ge's unique rap style, some netizens read "baby" as "North North" and evolved into the stalk of "North North Painting".

In addition, the popularity of this stalk is also related to the participation of stars. For example, Yang Mi sang this song at the New Year's concert, which further promoted the popularity of this stalk.
