Okay, the user sent "two-legs". Let me check the translation rules again. The first rule says to translate all content into Thai. The second rule states that if the content is already in Thai, leave it unchanged. The third rule is to provide only the translation without explanations.
So, "two-legs" is in English. I need to translate it into Thai. The direct translation would be "สองขา" which literally means "two legs". But I should check if there's a more natural or commonly used term in Thai. However, since "two-legs" is a compound word, the translation would be straightforward. There's no indication that the user wants a specific term or a different context. Therefore, the correct translation is "สองขา".
