Okay, the user wants me to translate "pre-schools" into Thai. Let me check the 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 as is. The third rule is to provide only the translation without any explanations.
So, "pre-schools" is in English, so I need to translate it. The Thai term for pre-schools is usually "โรงเรียนอนุบาล" or sometimes "โรงเรียนก่อนวัยเรียน". I should confirm which one is more commonly used. "โรงเรียนอนุบาล" is the standard term for preschools in Thailand. The other term might be less common or used in specific contexts. To be safe, I'll go with "โรงเรียนอนุบาล" as the primary translation. No need to add anything else since the user wants only the translation.
