One of my cousins learned a PCB design when he left. He said that the teachers there have a good teaching level and have worked as many senior engineers in the factory! He is over 40 years old and experienced. I feel that his teaching is ok! There is a teacher Li over there who has worked in the factory for more than twenty years! You can talk to that teacher when you have time! When my cousin was studying there, more than 30 students were studying PCB design. There are also computers specializing in PCB design!
