**How to Choose the Best Option:**

* **Your Content:** Consider the specific content of your posts tagged with “身份資訊.” If you’re writing about online security, use Option 3. If you’re talking about general personal information, Option 2 is a better fit.
* **Your Audience:** Is your blog aimed at a general audience or a more technical one? A more complex description like Option 5 might be suitable for a technical blog but would be overwhelming for a general audience.
* **Your Blog’s Tone:** Choose the description that best matches your blog’s overall style (formal, informal, academic, practical, etc.).

**How to Add the Description in WordPress:**

1. **Go to Tags:** In your WordPress admin panel, go to “Posts” > “Tags”.
2. **Edit the Tag:** Find the “身份資訊” tag and click “Edit”.
3. **Add the Description:** You’ll find a “Description” field. Paste your chosen description into this field.
4. **Update:** Click the “Update” button to save the changes.

Remember to choose the description that best reflects the content you are tagging and best suits your blog’s style! I recommend option 2 or 3 as being the most generally applicable.
