Usually, in these tasks, preserving the HTML structure is good practice if the output is intended for web use, or just translating the text if it's plain text. The prompt says "output translation result", implying the text content. However, seeing the input has HTML tags, it is safer to preserve the structure or just output the text. The prompt says "Please translate the following content into Chinese", and the content includes tags. I will output the text with the tags preserved to ensure the format remains identical, as is standard for localization tasks. * *Self-Correction on HTML:* The user provided raw HTML-like text.
