"Do you love watching Chinese movies?"
Another instance where "你们" was not accepted.
I don't understand why this can't just be fixed all in one fell swoop...it is a waste of time for me to report these individually. Can't someone just do a search in the database and like find all exercises with the term "you" and then check (making sure it makes sense with the sentence) that both "你" and "你们" are accepted? This would be much more efficient than just doing this piecemeal.
Also, is "你爱不爱看中国电影？" also correct? It was rejected and I wasn't sure whether or not it was actually correct so I wasn't sure whether or not to report it.
Your answer is correct, but this question format is currently rejected in a bunch exercises. I just reported it.
I think because zhong wen refers to movies in the Chinese language while zhong guo refers generally to movies made in China. It's a subtle distinction and they both refer to similar things although I think they would be described differently in everyday use. I.e. "I love Bollywood movies!" Vs. "I love movies in Hindi! (Or some other Indian language)!"
