**How to Use in WordPress:**

1. **Go to your WordPress Dashboard.**
2. **Navigate to “Posts” -> “Tags”.**
3. **Find the “語言評估” tag (it should exist if you used it in posts).** *(If it doesn’t, create a new Tag, enter the name “語言評估”, and paste one of the descriptions below into the “Description” field).*
4. **Edit the Tag.**
5. **In the “Description” field, paste the description you chose above.**
6. **Click “Update” (or “Save”).**

**Key Considerations when Choosing/Customizing:**

* **Your Blog’s Niche:** If your blog focuses on a specific language (e.g., Chinese), you might want to tailor the description to that.
* **Your Audience:** As in Option 3, think about who is reading your blog.
* **Keywords:** The descriptions include good keywords (語言評估, 評估, 語言能力, 測試, etc.).
* **Length:** Keep it concise but informative. WordPress search results often show descriptions in snippets.

Good luck! Let me know if you’d like any of these tweaked or if you have a different aspect you’d like emphasis on.
