**Key Considerations When Choosing:**

* **The Content of Your Posts:** What are the main themes and topics of the posts that will be tagged with this term? Choose the description that best reflects their content.
* **Your Target Audience:** Who are you trying to reach? Are they beginners or more advanced? Adjust the wording accordingly.
* **Search Engine Optimization (SEO):** While descriptions aren’t a primary SEO factor, they can influence user click-through rates. Avoid complex jargon if simplicity is better for your audience.

**How to add the description in WordPress:**

1. **Go to your WordPress dashboard.**
2. **Navigate to “Posts” > “Tags”.**
3. **Find the tag “贈與計算”. Edit it.**
4. **Locate the “Description” field.**
5. **Paste the description you’ve chosen into the “Description” field.**

I recommend starting with **Option 1** or **Option 2** unless your content has a particular focus. Adjust the description later as needed. Good luck!
