@beardalaxy I got my username from a username generator. I selected chinese usernames (I assume it just jumbled a bunch of Chinese symbols) and I got xianc. The 78 came from using command prompts random number variable.
I know Xian is an actual Chinese name but I don't know if Xianc is.
I guess you could pronounce it like you are pronouncing it in Pinyin, but I really don't care. I just think it looks cool.
