The enraged widower who mobilised victims' relatives to activism in the wake of the Wenzhou bullet-train crash, but then swiftly fell silent, has hit back at his online critics and conspiracy theorists who accused him of selling out to the government. Yang Feng's sudden disappearance from the public eye sparked speculation among internet users about whether his silence had been bought, with some questioning his motives and even his marital status. These included a claim that Yang demanded the Ministry of Railways give him exclusive rights to sell high-speed rail tickets in Wenzhou, Zhejiang, and his hometown of Shaoxing. But in the Guangzhou Daily yesterday, after a flurry of posts on his microblog on Monday night, Yang defended himself and called for reporting to be 'based on facts'. Yang's pregnant 'wife' Chen Bi, sister-in-law, four-year-old nephew and mother-in-law had been among at least 40 who died. The 32-year-old first burst into the media spotlight two days after the July 23 rail disaster when he instigated a protest at Wenzhou's morgue, which became a rally outside the city's government headquarters. The next day, however, he began refusing to accept media interviews and did not make an appearance at two further protests later in the week. On his personal Weibo microblog, Yang admitted that the right to sell tickets in the two cities had been the last of four demands in meetings with railways officials since July 29. But he insisted 'any profit would have gone towards a fund for relatives of the victims, those injured and relatives of those injured'. Among his other demands was that his unborn child be included in the list of the dead. Yang also admitted that he and Chen were not officially married at the time of the accident - although they held a ceremony in Wenzhou last year, the wedding had not been registered with the authorities.
