On 22 February 2008, "The Wall Street Journal" Online reported China's state-run news agency, Xinhua, issued a public apology for publishing a doctored photograph of Tibetan antelope running near the Qinghai-Tibet railway. Liu Weiqing, a 41-year-old photographer, was identified as the author of the work. He had reportedly camped on the Tibetan plateau since March 2007, as part of a series by the "Daqing Evening News", to raise awareness regarding the Tibetan bovid. He was also under contract to provide images to Xinhua. He has since resigned from "Daqing Evening News". Despite the impression given by the faked photo, the antelope are getting used to the Qinghai-Tibet Railway, according to a letter to "Nature" on 17 April 2008, from researchers of the Chinese Academy of Sciences.
