There’s a restaurant in central Taiwan that has decorated its floor space with those kind of (operating) antique-looking fans. After I saw my 3 year old daughter checking it out, I went over and turned it off, then felt the blades. They were metal, heavy and almost sharp [ETA: and the motor seemed quite powerful – it was putting out quite a breeze, rotating those heavy metal blades]. They could have easily broken one of my kid’s fingers if not severed them. I had a word with a manager, who listened with the typical Taiwanese smiling, respectful, embarrassed head bobbing earnestness while at the same time blowing me off entirely. I’m sure she started the fan again as soon as we left.
