Let me 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. You can 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 Nanjing 89DJ Wang Yilong DJ Training School, and sign up for an advanced class. I suggest you buy Juan DJ training at work, and then consider this for further study when you have money.
