Mr. Zheng is the only one in class. His curriculum is characterized by no theory, and it is basically a formula. The lecture is fast, the students ask few questions and there are almost no problems. Teachers don't like to answer questions, even if the answers are only rough answers, they are in less good mood and more bad mood. The focus of the course is to draw the base map, and the rest are rough. However, his business there is very good, which may be a herd effect. Some people say that since the quality of teaching there is so poor, why can he survive there for more than ten or twenty years? It must be that his teaching methods are useful and exist for a reason! Yes, everything is inevitable, such as the existence of cockroaches, mice and thieves. Everything good and bad will not be transferred by personal will, but it still exists! I sincerely suggest that friends who want to engage in clothing printing industry must buy some materials for self-study, and then go to training institutions to study after they have basic understanding and discrimination ability.
