【明報專訊】TAN ZUOREN, a mainland human rights activist who investigated tofu-dreg constructions in Sichuan in 2008, was given a five-year jail sentence for "inciting subversion of state power". He was released last Thursday (March 27), but he was taken away the same day. The next day, even his two daughters had no idea where he was, who was supposed to have regained his liberty.
