This morning, I was crossing the road when I saw this guy with the sign "No Smoking in this area". I thought to myself, wah, have they intensified the No Smoking Campaign to this extent? It did look like a great gimmick.
An European couple crossing the road with me was also tickled and asked the guy for permission to take a photo.
But no, this is not a gimmick. It was a serious matter. Some gas leakages were detected and there was a gang of workers looking for the source. In the meanwhile, the public was warned not to smoke, lest there be fireworks ahead of the next celebration in Chinatown. (^^)
