Yes I have told I should shave more often. Within 24 hours of not doing this, I get comments I look like a criminal (means like a pirate, blackbeard I guess). Back to the main point I get comments from people I know here, but never from anyone I do not know outside in the MRT, bus, train ect. I guess you may guess comments from classmates though, as I get it from co workers but I hope within reason accept that Taiwanese are like this.
