I have done numerical control, and personally feel that car maintenance and beauty are much better than numerical control. People in China are getting richer and richer, and more and more people buy cars, which has a bright future. Can do car maintenance and beauty, or be your own boss. More and more people are doing numerical control. Moreover, numerical control has no bottom, and the program machinery is constantly updated. If you choose numerical control, you must learn constantly at work, that is, learn by doing. Now your salary is four or five thousand yuan a month, and you work overtime every day. Very tired. Test it yourself.
