Workers with the meteorological authority in Qingzhen city, Southwest China's Guizhou province, prepare rockets, which contain chemicals that spur precipitation, to bring artificial rain to the drought-ravaged region, August 4, 2011. Most parts around the provincial capital Guiyang embraced a long awaited rain early Friday morning after rocket projectiles were fired into the sky at several meteorological stations when clouds formed around midnight Thursday.
