These guys and gals were cleaning out the sewers today. I love the "Chinese" hats with safety material on them. Christine exchanged a few (friendly) words with them - they were surprised to find out one of us could speak some Chinese. They told us to make sure we wore our helmets while on the scooter. I think they had a good laugh at a Chinese joke that was beyond us: the one who told us about the helmets said that his name was safety. As almost all Chinese jokes are wordplay/word-switch jokes, maybe the word for safe was part of his name? I don't know. They thought it was funny, though.
