(The reason why it is not included in the category of art is because we are mainly talking about how to use this aspect for marketing, not how to make a picture. Artists only need to complete the drawings according to the requirements, which must be the requirements of operational thinking. This course can be both hands-on learning and artistic learning. In short, whether it is operation or art, a picture with marketing thinking is a good picture! Only in this way can it be more conducive to conversion and making money.)
