My name is Giang. I come from Viet Nam. I've already graduate from Science University in Physics, but now my work is in IT field. I start study C# in 2013, but really study is 2014. My IT knowledge and english is not very good, but I know http://stackoverflow.com/ is a good IT website, so I often surf this website to find knowledge that I need. And I hope one day, I have enough knowledge to answer problems of other people.
