Okay, the user wants me to translate "line-drawing" 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, leave it as is. The third rule is to provide only the translation without any explanations.
So, "line-drawing" is an English term. The Traditional Chinese equivalent for "line drawing" is usually "線條畫" or "線描". Let me confirm which one is more commonly used. "線條畫" refers to a drawing made with lines, while "線描" is a specific technique in art, like in Chinese ink painting. Since the user just said "line-drawing" without context, "線條畫" might be more general and appropriate here.
Wait, maybe I should check if there's a standard translation. In art contexts, "line drawing" is often translated as "線描" when referring to a specific style, but if it's just a general term, "線條畫" could work. However, sometimes "線條畫" is used for "line art" in a broader sense. Let me make sure.
Looking up some references, "line drawing" as a general term is often translated as "線條畫", while "線描" is more about the technique. Since the user didn't specify the context, I'll go with "線條畫" as the safer choice.
Also, the user wants only the translation, no explanations. So the response should just be the Traditional Chinese term without any additional text. Alright, I think that's it.
