Travel is supposed to be a happy experience, yet people often neglect safety issues during their trips for various reasons. The consequences can range from an unpleasant experience that casts a pall over the trip, to physical injuries or even loss of life. Recently, everyone has been closely following the case of Lu Jun, a tourist from Beijing, who went missing on his way up Mount Tai. As of today, however, Lu has been missing for nine days. While search and rescue personnel have conducted a grid search, Lu still remains missing.
