The story has divided opinion on social media, but some users on the Weibo social networking site are angry at the - apparently unintended - implication that civil rights are associated with the US, and not China. "Doesn't this country have civil rights?" asks one user . Others are more troubled by flags being used at all. "China has guidelines for using the flag, you can't just use it for a joke," says one popular comment on the Caixin Online page . "If it was the Chinese flag falling, I think we would become a disrespected country." But not everyone's upset, and some users think the whole thing has been overblown. "You haven't done anything wrong," says one user. "There's no need to apologise."
