Okay, the user wants me to translate "remained stationary" into Thai. Let me check the rules again. The first rule says to translate all content into Thai. The second rule states if the content is already in Thai, leave it as is. The third rule is to provide only the translation without explanations.
So, the input here is "remained stationary," which is in English. I need to translate it. The correct Thai translation for "remained stationary" would be "คงอยู่นิ่ง" or "ไม่เคลื่อนไหว." Let me confirm the most accurate term. "คงอยู่นิ่ง" means "remained still," which fits the context. Alternatively, "ไม่เคลื่อนไหว" means "did not move," which is also correct. Depending on the nuance, but both are valid. I'll go with "คงอยู่นิ่ง" as it directly translates to "remained stationary." Make sure there are no explanations, just the translation. Alright, that's it.
