Mr. Xiaosheng Tan

According to the page of your personal details 
( in Baidu BaiKe. Currently you are the

with Hongyi Zhou, the CEO and the owner of Qihoo who was entitled as "the 
father of Chinese malware" by netizen.

So, do you represent your company to explain the issues? or Hongyi Zhou? or 
only yourself?
