I recalled a little-known past incident: I had retired for many years at that time. One day, a former colleague called me to say that a group of distinguished guests from ASEAN countries were coming to our country to participate in study tours and cultural exchanges. They would spend more time on ITE. For this subject, I was invited to teach Programmable Logic Controller, which is a high-end subject commonly used in industrial automation systems. The content includes hardware and software, and the hardware equipment is easy to accept without much difficulty. However, the software has five different types of language expressions ( Languages), all have their own strengths and are related, but each has a different way of writing. All ITE lecturers who teach this subject, except me, only know three at most, and I am a rare talent. And I have spent countless years honing my skills. I have practiced it (I have also taken some related courses, but the benefits are not much), I am afraid that I will not find any opponent in ITE.

These VIP students were teachers, engineers, masters and doctors, and they were inevitably a little uneasy. On the first day of class, I followed the course arrangements. As usual, I first understood the knowledge that needed to be used, and then reviewed and applied it through practice. I just found out. I feel that this field is their shortcoming. In fact, they are just ordinary people with nothing special about them. Learning requires time and effort. At this time, I was full of confidence to be their lecturer. At that time, there were department heads, principals and headquarters Some big shots came to watch my teaching.

This is just one of the five software languages. I have taught it repeatedly for many years. To be honest, it is just pediatrics. The content is the most basic common sense and application. At that time, Singapore was more advanced than other ASEAN countries in high technology. Some of them have heard of PLC and some have learned it. The learning process requires practice and is not something that can be mastered immediately. Of course, I teach easily and happily like a fish in water. No one doubts my ability and everything is under control. No one knows their leadership. The lecturer does not even have a primary school diploma. This is unprecedented and unheard of!

Due to the large number of students (more than 30 people), there are two lecturers to teach. The other is a lecturer from the relevant department who has taught this subject for many years, but he does not have the courage to be the leading lecturer (actually, there is no distinction between the principal and the deputy), facing a group of distinguished guests. Student. I have said before that I like the laissez-faire teaching method. All key questions are solved on the spot and the answers cannot be found in the textbooks. This puts a lot of pressure and test on him, and he is unable to respond to the questions from the students. In contrast, he also He can only be an assistant, even if he is willing to teach me, he can't even say that he can't do what I teach. The inappropriate and incompetent instructor brings shame to ITE! He misleads the students. Because of his incompetence (cannot solve the errors and problems of the software written by the students) , but it has contributed to my image and prestige, which can be regarded as a great merit. He is happy that he gets the same salary as me, and everything is done because I am courageous and carefree, and everyone will be happy when everything ends successfully!
