Social media speculation over the whereabouts of China's highest-profile entrepreneur swirled this month after news reports that he missed the final episode of a TV show featuring him as a judge, amid a regulatory clampdown by Beijing on his sprawling business empire. Ma had not appeared in public since a late-October forum in Shanghai, where he blasted China's regulatory system in a speech that set him on a collision course with officials, leading to suspension of a $37-billion IPO of Alibaba's financial affiliate Ant Group. Tianmu News, a news portal under Zhejiang Online, which is backed by the provincial Zhejiang government, first reported that Ma had met with the teachers via a live video conference on Wednesday. The Jack Ma Foundation said that Ma participated in the online ceremony of the annual Rural Teacher Initiative event on Wednesday. Alibaba Group also confirmed that Jack Ma attended the online event. In the 50-second video, Ma, dressed in a navy pullover, spoke directly to the camera from a room with grey marble walls and a striped carpet. It was not clear from the video or the Tianmu News article where he was speaking from. He addressed teachers receiving the Jack Ma Rural Teachers Award, who in previous years would have attended a ceremony organised by the Jack Ma Foundation in the Chinese seaside city of Sanya. 'We cannot meet in Sanya due to the epidemic,' he said in the speech, which did not discuss his whereabouts. 'When the epidemic is over, we must find time to make up for everyone's trip to Sanya, and then we will meet again!'
