**Option 1: Concise & Clear**

* **Clarity:** Keep the description clear and concise to avoid misunderstandings.

Remember to add this description in the “Description” field of the tag when you create or edit the tag in your WordPress admin panel. You can also use the “Slug” field to create a user-friendly URL for the tag (e.g., `dai-fu`). I recommend using the `dai-fu` for the slug.
