**How to use this in WordPress:**

1. **Go to your WordPress admin panel.**
2. **Navigate to “Posts” > “Tags” (or “Categories” if you are using categories instead of tags).**
3. **Find the “興趣分享” (Sharing Interests) tag.**
4. **Look for the “Description” field.**
5. **Paste one of the descriptions above into the “Description” field.**
6. **Click “Update Tag” (or “Update Category”).**

Choose the description that best fits the tone and purpose of your website. I would recommend Option 2 if you want to provide users with as much information about the posts as possible.
