Here are a few options for the WordPress `post_tag` description, catering to different levels of detail and SEO considerations. Choose the one that best suits your needs:

**Option 1: Concise & Descriptive (Best for general use)**

* **Description:** 探討未婚同居的現況、權益、挑戰，以及相關法律與社會議題。 (This translates to: Exploring the present situation, rights, challenges, and related legal and social issues of unmarried cohabitation.)

**Option 2: Keyword-Rich (Good for SEO, slightly less natural)**

* **Description:** 關於未婚同居、同居生活、同居權益、未婚夫妻、同居關係、同居協議、同居法律的相關文章，幫助你了解未婚同居的方方面面。 (This translates to: Articles about unmarried cohabitation, cohabitation life, cohabitation rights, unmarried couples, cohabitation relationships, cohabitation agreements, and cohabitation law, helping you understand all aspects of unmarried cohabitation.)

**Option 3: Conversational & User-Focused**

* **Description:** 對未婚同居有疑問嗎？在這裡你可以找到關於未婚同居的一切，包括法律、權益、生活方式等。 (This translates to: Have questions about unmarried cohabitation? Here you can find everything about unmarried cohabitation, including laws, rights, lifestyles, etc.)

**Option 4: Focusing on Legal Aspects (If your content skews legal)**

* **Description:** 關注未婚同居的法律框架，包括權利、義務、財產分配、以及相關的法律案例分析。 (This translates to: Focusing on the legal framework of unmarried cohabitation, including rights, obligations, property distribution, and related legal case analysis.)

**Key Considerations when choosing:**

* **Your Content’s Focus:** If your posts cover various facets, Option 1 or 2 is good. If heavily legal, use Option 4.
* **SEO:** Option 2 is designed to attract more searches.
* **Target Audience:** Consider their level of knowledge and preferred language style (formal vs. casual).
* **Word Count:** WordPress tends to truncate longer descriptions, so keep it relatively concise.
* **Use of Keywords:** Keywords like “未婚同居” (unmarried cohabitation), “同居” (cohabitation), “權益” (rights), “法律” (law) are important. You can experiment and see which keywords attracts your target audience.
* **Keep it Natural :** While SEO is vital, make sure the description sounds natural. Avoid keyword stuffing.
