**Choice Considerations:**

* **Keyword Optimization:** Consider adding relevant keywords within the description such as 慈善 (charity), 醫療 (medical), 教育 (education), 環保 (environmental) if your content covers these areas.
* **SEO:** Keep it relatively concise—WordPress tag descriptions are often not indexed as heavily as post content. But using keywords will still help a bit with SEO.
* **Audience:** Is your audience primarily familiar with Ciji? If so, you can use a more concise and engaging description. If they are less familiar, you might want to include a bit more information about what the organization does.
* **Your Website Style:** Choose the description that best fits the overall tone and style of your website.

I recommend choosing the option that best suits your content and target audience! Remember to enter the description in the “Description” box in the tag settings when creating or editing the post tag in your WordPress admin.
