This is called "jumping". But personally, I don't recommend that you download poor dance teaching software. The movements in it are not detailed at all, and you have changed a lot yourself. And the teacher's sense of dance is also very general, which is not recommended. Why not go to Youku and download the teaching of each dance directly? There are many original Korean dances, but the teaching is very detailed, and the movements are also separated from the original. Of course, this is a family statement, you choose according to your actual situation. You can ask questions at any time. I hope I can help you.
