You are likely to get more responses if you’ll get Google to translate your posts into English. I heard of a study recently that suggested that students who wrote papers in Chinese and had Google translate them got better grades than students who wrote them in English, which suggests that Google is doing a pretty decent job these days.
IS your SiteSetting.default_locale set to %w(zh_CN zh_TW ko ja), if so, I think it should be skipping that test. But if not, you should make sure that your default_locale is set to zh_CN or whatever is appropriate.
