Abstract: The unique teaching style of mechanical and electrical products attracted me deeply in the first class, which made me have a major change in the understanding of many concepts and concepts, reflected and redesigned myself, and learned and understood concepts, advanced technologies and many related information through storytelling and lectures, which were unheard of before. Some thoughts on the teaching content of mechanical and electrical products, the teacher's introduction of this new technology, and the introduction of his students' examples, This subject has aroused my interest and feelings in my professional life. On another level, I realized how to use the limited time to learn more knowledge that is beneficial to future development. "Being an engineer in engineering drawing, let me face it" deeply realized a teacher's rigor and responsibility for science and technology, and thus I had a belief in the teacher.
