Identifiying language

i need help identifying this language, any help will be appreciated.
the word is
ɥao
i'm not sure if it's an upside down h, but it looks like it. This means goodbye in some language.

 

Not to be an asshole, but all you need to do is google. Anyways, its Russian.

 

I tried looking for it, it's a bet my teacher made with the students, he says it's not Russian and we already identified Russian as something other word.

Yes that is correct. It's actually "чао" not "ɥao".
