Self-study: long time, poor effect. But it costs nothing. This way of learning, you need to find tutorials everywhere on the internet, which will be very complicated. It takes a long time for the tutorial you read to be integrated and applied to your own work as your practical skills. Often most people give up when they can't hold on. Some technical things often need someone to discover.

Enroll in class: short time, good effect, and need to pay for study. The advantage of this learning method is that all teachers in the industry know that you are studying, and at the same time, your learning course is systematic and has been tested by many students. In this respect, your learning efficiency and effect will soon be very good.

Then it should be noted that there are various training courses on the market now, so how to choose a good training course is also a very elegant thing. If you choose wrong, you will suffer. Personally, I suggest looking for the kind of training class opened by the master, like Shantou's strength to build this kind. If you are satisfied, please accept it.
