Ni chuan. means well, I don't know what the Ni stands for but Chuan is
spring. Ni possibly means curse if it's one of the chinese words I don't
know. 

Well, all I really know is that "ni" is used as "you" in Chinese <I think>.
 So Nyannichuan would probably mean "Young Girl you Spring."  I guess in a
way it would make sense...

But then again, I am the last person to consult when it comes to Chinese,
being Chinese but NEVER learning the language, let along Romanization of
Chinese words. ^_^
