- block the other person's weapon (even if it is a fan) with your weapon (which may also be a fan), not with your hand. Especially if the other person's fan has metal ribs
- when lion dance training after taking such an injury, don't lift the head when you have to hold the mouth shut
- when walking through door frames, make sure you fit through the doorframe. Do not get distracted by small dogs attempting to run outside, and definitely do not clock the alleged "funny" bone on the doorframe to the point where you lose all feeling in your hand for a little while (preceded and followed by HOLEY SHEET THAT HURTS), especially if it's the arm with the hand that doesn't have aforementioned wrist injury on it
Not that this has ever happened to me, definitely not in the last week, because who would be so dumb.
