On 3 May the central propaganda department issued new media guidelines designed to downplay coverage of the Qinghai earthquake and recent school attacks in order to promote the Shanghai Expo. After four violent attacks on schoolchildren in a month, reports of the incidents began to be withdrawn. The guidelines also specify that reports on the expo use only official state-endorsed Xinhua sources. Hong Kong newspaper Apple Daily has confirmed it was denied accreditation to cover the Expo, and the home of activist Feng Zhenghu was raided on 19 April, after he attempted to launch his own online expo of judicial injustice.
