Okay, the user sent "red-bed". Let me check the translation rules again. The first rule is to translate all content into Vietnamese. The second says if it's already in Vietnamese, leave it as is. Third, only provide the translation without explanations.
So "red-bed" is an English term. I need to translate it into Vietnamese. "Red" is "đỏ" in Vietnamese. "Bed" is "giường". So "red-bed" would be "giường đỏ". Let me make sure there's no existing Vietnamese term for "red-bed" that's different. Maybe "giường đỏ" is correct. I should output just "giường đỏ" without any explanations. The user wants only the translation result. Alright, that's it.
