Just as a note, Chinese isn't a language. There is a chinese written language, but people in China actually speak a wide variety of languages. These languages are not mutually intelligible. Thanks to efforts of the Chinese government, apparently most Chinese people know what is called Standard Chinese, the official language of China which is mostly based on Mandarin. However, a lot of Chinese populations in other countries such as the US tend to speak Cantonese instead.
So saying Chinese as an answer isn't quite as simple as it sounds. Knowing one or more Chinese languages would probably be really useful though.
