I just came back a few years ago. Let's talk about evaluation first. The teacher's level is quite high, and his teaching is also very dedicated. But to tell the truth, two or three of our 20 students in the first phase didn't study. It is up to individuals to mention their own shortcomings. Accommodation arrangements are ok and need to be strengthened. In terms of maintenance practice, we got a lot of pallets to be repaired, but if we want to repair the customer's machine, the teacher is afraid of being damaged by the customer and expanding the fault. . . .
