My brother said that in fact he did not dare to believe now that he is now at data center security, I said you can’t believe what he said, because he felt that people like him in a lot of time not sure for what to do, I think my brother who is a very confident person, how to work on their own not so confident. I think if I was my brother, I would be happy to work in the data center security for myself, many times when you want to do a thing, you must want to know you do this thing, you want what kind of effect this way, you will know what you should do next question.
