The volunteers, all current college students, were surprised to hear of the massacre for the first time in their life.
'Guide to survive an earthquake' as such words: take shelter in hospitals and schools. In China, Netizens summarized after the two major earthquakes while the school buildings always collapse first, if not alone due to poor building quality, that people should look for government buildings instead, because they always stood.
