**How to Use in WordPress:**

1. **Go to Posts -> Tags** in your WordPress dashboard.
2. **Enter the Name:** `乳製品` (Rǔzhǐn)
3. **Enter the Slug (Optional):** WordPress will usually automatically generate a slug (like `rǔzhǐn` or `ruzhipin`). You *can* edit it if you prefer a different URL-friendly version. It’s generally a good practice to use a plain form like pinyin for the slug, especially to avoid problems with URL encoding.
4. **Enter the Description:** Choose one of the descriptions above and paste it into the “Description” field.
5. **Choose/Create Parent Tag (Optional):** If you want to organize this tag with other category/tags. (This is optional.)
6. **Click Add New Tag.**

Remember to choose the description that best fits the content and overall focus of *your* website. Always use Traditional Chinese characters for your website content if you are targeting areas that use Traditional Chinese. Good luck!
