In Beijing? As far as training institutions are concerned, there are many people doing this in Beijing at present, but they are mixed. I suggest you go to the school training institution to get to know it on the spot first. It needs to be worth the money.

I know that the JAVA class in the training department of Tsinghua University Computing Center is quite good. Small class teaching is the first project in China. Tsinghua University has a strong faculty! This semester lasts for four months. If the tuition fee is zero, it seems more than 12800! I have friends studying there. And they also recommend high-paying jobs. That friend of mine is the job that the school found. Specifically, you have to go to the school yourself.
