Chinese tend ancestors' graves on Tomb Sweeping Day Chinese residents tend their ancestors' graves during the annual Qingming or Ching Ming festival, also known as Tomb Sweeping Day, at a cemetery in Dagantangcun, 30 kilometres east of Beijing. The public holiday is a traditional day of remembrance for the dead, where it is customary for Chinese to sweep off the gravestones and air out the ash boxes of their loved ones. IMAGES
