I’m sure that most of the old salts on here have been to the Yanshui Fireworks Festival several times, but if you haven’t, I can’t recommend it enough. I’m coming to the end of my first year here pretty soon, and I can’t believe that I almost didn’t go to the festival (it was on a school night.) If you’re new in Taiwan, put this one on the top of your list.
Here’s a video I made of the festivities: http://fadeoutfade.in/yanshui-fireworks-festival/
