Chinese "ni hao" is mis-spelled in bot's "hello" response

When a user says "hello!" or "hi!" the bot responds with a random language's greeting.

The Chinese language response is misspelled as "niihau".

"niihau" is the smallest Hawaiian island. http://en.wikipedia.org/wiki/Niihau
"ni hao" is the correct pinyin romanization of 你好, or the equivalent of "hello" in Chinese. http://en.wikipedia.org/wiki/Ni_hao
