What network security training institutions are there in Taiyuan?

I don't know what's in Taiyuan. I am in Beijing now. I know something about Beijing. The only network security major in Beijing is David's network security training. You can have a look at their website. There are video tutorials and e-books, all of which are free. You should learn a lot of knowledge and receive some training. I wish you a real skill as soon as possible:)
