"He has lived in China. He can speak fluent Chinese."

Translation: 他在中国住过，能说流利的中文。

[Gustopher94]

Why is it 能 as opposed 会 when its a learnt skill?

[WillowsofXihu]

I agree. The normal formula is会+说(语言). Unfortunately this is an area the Duolingo Chinese course often messes up on, partially due to using 会 primarily as a kind of magical "future tense equivalent" wand, which affects the accuracy/authenticity of many sentences. Granted, 会 vs. 能 usage is a very complicated topic, with many grey areas even for native speakers.

会说（语言），能说【流利的】（语言）are both idiomatic. Not sure how to explain since both are technically not wrong and this is something picked up through exposure to the language (read, listen, etc. more)

他住过中国 ... Is this also an acceptable way to say this? Or 他以前住过中国?

[Patrick_Dark]

This exercise needs to accept "漢語" in lieu of "中文".

[hxuanmin]

Do we need 得 before 流利 here? Like this, 能说得流利。

Why does the spanish one demand "language 的 fluent", but this one "fluent 的 language"?
