Yeah I am going to a trip to Taiwan in X units of time for Y purpose (I want to avoid being doxxed) and the event organizers told me I need a Chinese name (idk for what exactly tbh).
So there you go. I’m pretty sure the chinese name means something like “complete enlightenment” (or at least that is a possible interpretation, which I’m going with cause its cool af).
I kinda wanted to do something with “xiao” because I find it cute and almost girly (although I think Chinese people wouldn’t find it as such), but it’s fine I guess.

You’re probably fine to use it, especially if you feel it’s similar to your og surname (evoking its pronunciation/first syllable, or its meaning). It’s just a consideration that might come up, definitely would feel weirder if you were a white westerner haha. Historically non-han peoples sinicizing took particular Chinese last names, for example, among Hui ethnic people who practice Islam, some common last names are 胡 hu/hussein 马 ma/mohammed 穆 mu/also mohammed
