In addition, Internet companies have launched a number of initiatives to help quake victims.
Baidu, the country's biggest Web search engine, launched an online application that provides information about survivors and missing people. At least six survivors were found by their family members after their details were posted on the platform.
Renren, a Facebook-like social network, and Qihoo 360 Technologies, a Beijing Web company, have also launched similar platforms.
Such services caught the public's attention in China a week ago when Google used its Person Finder application to post information on missing persons in the aftermath of the Boston Marathon bombings.
China's largest navigation provider by market share, AutoNavi, said it is providing services to rescue teams in Sichuan. The company also pledged to offer free downloads of its offline navigation app to the public.
