Here are a few options for the WordPress post_tag “成人” (Chéngrén – Adult) in Traditional Chinese, along with explanations of why they work:

**Option 1 (Concise and Direct):**

* **描述 (Description):** 與成年人相關的文章。
* **(Pinyin: Yǔ chéngnián rén xiāngguān de wénzhāng.)**
* **(Translation: Articles related to adults.)**
* **(Why it works):** Simple, clear, and uses the core keyword “成年人” (adults). It’s easily understood by a broad audience.

**Option 2 (Slightly More Specific):**

* **描述 (Description):** 關於成人的生活、議題與體驗。
* **(Pinyin: Guānyú chéngrén de shēnghuó, yìtí yǔ tǐyàn.)**
* **(Translation: About adult life, issues, and experiences.)**
* **(Why it works):** This expands on the meaning, including topics that frequently relate to adults — life topics, concerns, and experiences

**Option 3 (For News or Current Events):**

* **描述 (Description):** 與成人相關的社會新聞、政策、及焦點議題。
* **(Pinyin: Yǔ chéngrén xiāngguān de shèhuì xīnwén, zhèngcè, jí jiāodiǎn yìtí.)**
* **(Translation: Social news, policies, and key issues related to adults.)**
* **(Why it works):** This would be perfectly suited for a news or current affairs website, framing articles in the tag as relevant to grown-ups (i.e. adults), with a focus on issues, politics, and social news.

**Option 4 (If the Tag is Used for General Information):**

* **描述 (Description):** 成人相關資訊、知識與資源。
* **(Pinyin: Chéngrén xiāngguān zīxùn, zhīshì yǔ zīyuán.)**
* **(Translation: Adult-related information, knowledge, and resources.)**
* **(Why it works):** This description is ideal if the posts tagged under 成人 are a mix of factual, educational, and resource-related content. It targets a broad demographic by using general phrases.

**Key Considerations for Choosing:**

* **Your Website’s Content:** The focus and style of your website are important.
* **Target Audience:** Who are you trying to reach with this tag?
* **Content of the Tagged Posts:** Are the posts mainly news, articles, resources, or other?
* Choose the option that best represents what your blog or website offers for that specific tag.

I recommend using the Option 1 (Concise and Direct) unless you have a good reason to use a more specific description. If the scope of your blog is wide, a more encompassing description can always be beneficial.
