Don't believe it, there are too many liars. I know many people who have been cheated. Be careful. Learning DJ is best to find a formal training institution and give you a suggestion. If it is for work or hobbies, I suggest you buy a tutorial, then buy a set of second-hand equipment and practice at home with the tutorial. Equipment is lower than school fees. Learn and equip, kill two birds with one stone. If you want to compete or improve your DJ level, I suggest you go to some well-known schools, such as Wang Yilong DJ Training School, and sign up for an advanced class. I suggest you wait for a job and consider taking this course when you have money. If you want to buy Juan DJ training class, the credibility is very high, you can Baidu it.
