What is the difference between Shang's "dark horse", "Dana" and "Shang Silicon Valley"?

These brands are headquartered in Beijing, and there are many choices to learn it technology in the capital Beijing. You can compare your own judgment through investigation. There are too many water forces on the internet, and all the news is not credible.

Extended answer:

When I was in college, most of my studies were academic, starting with basic studies. Dark horse has heard of it, but it seems not as good as the former. I have a classmate who studied from Dana, and the effect is not very good. This subject mainly lies in doing more projects, with a good foundation and a little effort. This business is definitely not fat.
