If you want to learn a major, you'd better take a class. In addition, the choice of training institutions is very important. If you want to learn something practical, I suggest going to New Orange College. They have real e-commerce projects, and they will get started quickly while learning. I opened a Taobao shop myself, just to learn the art of web pages, and went to the New Orange Electric Business School for training and registration, just opposite Renmin Road. After that, my friend also went there to study.
