Chinese as a foreign language

From Teflpedia

Chinese as a foreign language is Chinese (particularly Mandarin Chinese) as a foreign language.

In Chinese, the term used is 中文作为外语 (pinyin: Zhōngwén zuòwéi wàiyǔ).

The number of Chinese learners is increasing as China develops economically.

The grammar of Chinese is relatively simple, however the tones are a bit of a nightmare.
