Wuhu is not very clear. The training of Zeng Feng PLC is still very good. I looked up many training institutions on the Internet, and then I heard a friend introduce this one. After listening for a long time before studying, I decided to sign up. I feel good about it, too. Well-equipped, the trainer has a good attitude and feels that what he has learned is very practical. I learned all the knowledge of Siemens there.
