Beibei. Ronghao Li's song Beibei has only one word. Beibei is a Divine Comedy that you can remember the melody as soon as you listen to it. The total duration of this song is only 4 seconds, and the lyrics are only "Beibei" (the homonym of baby). It is precisely because the song is too short that many netizens feel "out of touch" when listening to this song. I have to say that Ronghao Li is really stubborn.
