**How to Choose & Apply in WordPress:**

1. **Consider Your Content:** Think about the *types* of content you’ll be tagging with “攜帶數量”. What are the common topics? Are you focusing on limits, or simply the raw number?
2. **WordPress Tag Interface:** When you create or edit the tag in WordPress, look for the “Description” field. You’ll paste the suggested description into this field.

**Example:**

Let’s say your blog covers travel tips. You’ll be writing posts about baggage weight limits, liquid restrictions at airports, and how many duty-free items you can bring back. Option 2 or 3 would work well in this situation for tag description.
