This is a familiar sight at Wong Tai Sin temple, by far the busiest temple in HK. Worshippers burn insense in great numbers so one gets a 'spiritual' experience as the air is filled with smoke. These people on the photo are trying to reach the shrine further to the right where they insert their insense sticks and make prayers. With so many people around, it was difficult to get a clean shot and unavoidable not to crop out some heads..
