For the data processing of the company, a good data center security is really important, I think we do in the data processing, if I think data center security not so reliable, then I think it will not go well, the fact that the data center security have their own part in I will, have my own opinion, but I think I still don’t do it, in fact our data center security is pretty good, at least I think no matter what, my friends in many ways to do well, but I think our company bought data center security really well, at least we will use when worried about security.
