Samuel Chan And Ron Ng, have been filming for "The Four great constables" at 《藍田石礦場》 filming an outdoor scene, and Samuel was to film a "Falling off a cliff" scene, but only managed to film him on the edge of the cliff, because of safety reasons, and had to wear a safety harness, to film this scene. As for Ron, he had to climb a sandstone, Rock, at the cliff edge, and he was wearing his heavy costume as well as safety protection for the hands and the legs, in case of injury. Ron must prepare for filming, next month he will have to be filming out door scenes, with many fighting scenes, which will be a hard time for him. Source: http://ron-site.blogspot.com/
