Detained celebrity blogger Xue Biqun, known as Xue Manzi on Sina Weibo, boasted that he used to be busier than a minister with endless invitations.

The noted venture capitalist was detained last month for alleged group sex with prostitutes. His detention sent ripples across the Chinese cyberspace as he was a star blogger with 12 million followers on Sina Weibo, a Twitter-like blogging service, and was seen as an "online crusader for justice".

On Friday, in a Beijing detention center, the avuncular figure recalled his journey to becoming an influential online voice.
