I always find such guidelines strange. Like I get the intention is to share some experience, but I rarely find the intended way of anything enjoyable at all. Even western traditional etiquette is weird. I shall hold the fork in my right hand and you can't stop me aunty! My tea shall be hot juice! And my side shall be mixed with the sauce and meat into a big ol pile before consumption!
I do that too and I couldn't properly cut anything with the knife on my left hand if my life depended on it lol. It's interesting that I don't think anyone taught me to switch, I just instinctively did that and they rolled with it.
