20 14 in Xiamen university, I saw the work of Wang Bo's retoucher from my colleague's mobile phone. After all the communication was done, I was going to come to him as a student. Later, due to some reasons in the store, the matter came to an end. Although I didn't study, I often sent him some of my own films, but he always helped me point out my shortcomings, which is also my shortcomings, not just the problem of post-photography. Later, in June of 15, I really wanted to see Mr. Wang Bo, so I signed up and came directly without saying anything. Bogo's lectures are easy to understand and very detailed, and students can deeply understand and remember them. And constantly let us feel the aesthetics, let us improve this piece. He often tells us that a good retoucher can't retouch pictures only by technology. He must have a more outstanding aesthetic concept than ordinary people, which I also keep in mind. I'm going to graduate soon, but I'm still a little reluctant. I will never forget that I was a disciple here when I was studying in a map training institution! Wu Dashuai.
