Okay, the user wants me to translate "sub-section" into Traditional Chinese. Let me think about the correct term. In Chinese, "sub-section" is commonly translated as "子節" when referring to parts of a document or section. I should make sure there's no other possible translation that might fit better. Since the user specified Traditional Chinese, I need to confirm that "子節" is indeed the traditional form. Yes, it's correct. No need for any explanations, just the translation. Alright, that's it.
