It's good. Several of our colleagues are studying there. They are more professional and formal, and the textbooks are written by themselves. They are very suitable. I bought the tutorial first and read it. It's really good. After learning on the spot, it helped me a lot. Now I am very skilled in Mitsubishi, Siemens, Panasonic, Delta and Xinjie. I studied Mitsubishi and Siemens. The students who graduated together at that time are now electrical engineers in this field. Last time I went back to Longfeng together, I found it getting better and better. I hope my business is booming!
