Okay, the user wants me to translate "non-european traits" into Traditional Chinese. Let me check the rules again. The first rule says to translate all content into Traditional Chinese. The second rule states that if the content is already in Traditional Chinese, output it unchanged. The third rule is to provide only the translation result with no explanations.
So, the input here is "non-european traits". Since it's in English, I need to translate it. The direct translation would be "非歐洲特徵". Let me confirm that "non-European" translates to "非歐洲" and "traits" to "特徵". Yes, that seems correct. I should make sure there's no existing Traditional Chinese version, but since the original is in English, there's no need to check the second rule. Just output the translation without any explanations. Alright, the answer should be "非歐洲特徵".
