How does the dance company play with numbers and get four companies?

How to play with the numbers in the dance troupe? Press the arrow keys, press the jumping space when the first space is about to land, and then press the space when the second space is about to land, so keep pressing and practice finding the rhythm. Of course, the hand speed should be fast enough to hit the direction indicated by the arrow accurately and timely. The advantage of continuous jumping is that the sound is small and it is not easy to hit you.
