**How to choose the best option:**

* **Audience:** Consider your target audience. The more technical the audience, the more detailed the description can be.
* **Purpose:** Do you want to simply categorize posts, or do you want to provide a brief explanation or encourage clicks?
* **SEO:** If search engine optimization is a priority, choose a description that includes relevant keywords (e.g., “全球經濟形勢” – Global Economic Landscape).
* **Space:** WordPress tag descriptions often have a character limit. Choose the option that fits the space available and is most informative within those limits.

I recommend Option 2 or 3, as they provide good context and are slightly more detailed than just a keyword. Remember to adapt the description to fit the specific content of your website.
