**How to use within WordPress:**

1. **Go to your Post Edit Screen:** Inside the WordPress admin area, go to the “Posts” section and either edit an existing post or create a new one.
2. **Find the “Tags” Box:** Scroll down to find the “Tags” meta box on the right-hand side (or sometimes below your content).
3. **Add the Tag:** Type “零利率” into the “Tags” box and hit Enter or click the “Add” button.
4. **Edit The Tag:** Click the tag. Wordpress usually allows you to link straight to the edit screen for the tag (or to select “Manage”). If you can’t find the direct “Edit” link, go to “Posts” -> “Tags” in your admin menu.
5. **Add Description (if available):** In the tag edit screen, you should find fields like “Name,” “Slug,” and “Description.” Paste or type your chosen description into the “Description” field. Be sure to save the changes.

Choose the option that best aligns with the content you’re tagging. If you’re writing about the broader impact on the economy, Option 2 is excellent. If your focus is on central bank actions, consider Option 3. If it’s for general tagging, Option 1 or 4 would be suitable.
