If you want to learn ps, you still have to rely on yourself. 99% of the basic knowledge of network artists is self-taught, and no one will spend time teaching a person who can't do ps to do design. However, there are still many online tutorials in this area. It depends on your own practice. At present, many system groups in this field say that ps is taught for free, but they always feel that they are up to no good. Don't believe it. Just don't contact. People who are cheated feel that they will not be cheated before they are cheated.
