How do you understand the dj's work of playing, receiving and cutting songs?

Here is a simple answer for you. If you don't know, you can add my contact information.

Receiving songs is mixing. This CD player has two or four CDJ (for playing songs). One plays a song and then receives another CDJ song in various ways. It should be perfect so that people who hear it will not think that the next main function is to make people dance.

Then instead of cutting the song, you lock the cue (also called the tangent point and breakpoint). The purpose is that you cannot directly connect to the next 0:00:0 1 when mixing. You have to choose the right part of the mixing point of the song being played (referring to the next song), and then lock (pause the song in that part). Hope to adopt
