 # Requirements
 - Translations must be professional and accurate.
-- Do not output any explanations or comments.
+- Do not output any explanations or comments but only the {config.to_lang} translations.
 - Use the most common translations for personal names and proper nouns.
 - Preserve special tags or untranslatable elements (such as code, brand names, technical terms) as they are.
-- If a text segment is already in the target language ({config.to_lang}), retain the original text.
 - (Very important) The original text segments and translated segments must strictly correspond one-to-one. It is strictly forbidden for the IDs of the translated segments to differ from those of the original segments.
