Here are a few options for a description for the WordPress post_tag “海外留學” (Overseas Study/Study Abroad in Traditional Chinese), depending on the nuance you want to convey:

**Option 1: General & Concise**

* **Description:** 探索世界，拓展視野。有關海外留學的資訊、經驗分享和申請指南，助你實現留學夢。 (Explore the world, broaden your horizons. Information, experience sharing, and application guides for overseas study, helping you achieve your study abroad dream.)

**Option 2: Highlighting Resources & Practicality**

* **Description:** 關於海外留學的實用資訊，包括簽證、學位選擇、住宿、生活指南以及獎學金等等。讓你輕鬆規劃留學生活！ (Practical information about overseas study, including visas, degree options, accommodation, living guides, and scholarships, etc. Making it easy for you to plan your study abroad life!)

**Option 3: With a Focus on Community**

**Explanation of why these work:**

* **Clear Language:** The descriptions use straightforward and easily understandable Traditional Chinese.
* **Keyword Focus:** The descriptions naturally include the main keyword “海外留學”.
* **Appeal to the Target Audience:** These descriptions aim for prospective students wanting to study abroad and want to address their primary interests.
* **Conciseness:** WordPress post tag descriptions should be relatively short, so these are all within a reasonable length.
* **Focus on Benefits**: They highlight benefits like expanding horizons, ease of planning (practical benefits) or connection with others and inspiration (emotional benefits).

When choosing, consider:

* **Your website’s overall tone:** Is it practical and informative, or more inspirational?
* **Your target audience:** What are their main concerns and needs?
* **Other tags:** Think about how this tag fits with your other tags and category strategy.

I would suggest **Option 1 or Option 2 (based on whether you focus on practical application) or Option 3 (based on community)** as a good starting point, these are excellent and quite flexible. You can always adjust the wording slightly to perfectly fit your needs. Remember to save your description when adding the tag in your WordPress dashboard!
