Zhang Feng Yi has been very fluent in his native language, Mandarin, since childhood. However, because he has worked in the entertainment industry for a very long time, Zhang Feng Yi also speaks and understands English. Still, his fluency in English does not match his native language, Mandarin. As a writer of this particular article, I'm not entirely sure, but Zhang Feng Yi might also understand some other local languages spoken by Chinese people, especially where he is from.
