It seems to be a popular software in Korea that teaches street dance through virtual tasks. There are desktop dolls dancing in it. You can choose music, then the dolls dance, and you can match them freely. For example, you can use the music of Bao Er NO and 1, and then do the best moves in An Qixuan. This software is called D-Player. It has a special website and can update tracks at any time. But this is Korean software, and all the tracks are basically Korean and Japanese ... You can try Thunder and search D-Player.
