Wuxi Dana, newly built, with a small base, but I heard that the national unified teaching is just a video;

Wuxi NIIT, China headquarters, should be good, but some seniors say it's average, mainly on their own;

Wuxi ChinaSoft International, training employees for its own company, is ok, but its business technology is not good, personally.

I recommend Wuxi Dana, who has done a lot of advertisements, is famous and rich.
