I don’t have to worry about data center security inside the company, because there is a special person in charge of the data center security, so I really can rest assured. Some time ago, friends have been to me said is very important in the data center security, is the our company should have a special person to be responsible for the data center security, then I think his words are justified. Then I will and also the leadership of a few discuss the next to the data center security importance to them, said, they also feel that it is necessary to make special person responsible for the data center security. Now we have set up such a department, so the things we cannot too much worry.
