**How to Use in WordPress:**

1. **Log in to your WordPress dashboard.**
2. **If you are editing a post with tag “土銀” already attached:** Open the post-edit screen. In the tags section, there should have an edit icon that you can mouse-over (often a pencil). Click this to edit the tag parameters.
3. **If you are adding the tag:** Go the post’s edit screen to set up or edit tags. Clicking on the plus ( ‘+’ ) sign will allow you to add a new tag. Type “土銀” into the name. Most WordPress installations will create an appropriate “slug” which is the URL-friendly version. Add the description in the “description” field.
