Here are a few options for a description for a WordPress post tag titled “合法” (Hé Fǎ, meaning “Legal” in Traditional Chinese), catering to different approaches:

**Option 1: Concise and Direct**

* **Description:** 代表符合法律規定的事物、行為或活動. (Dài biǎo fú hé fǎ lǜ guī dìng de shì wù, háng wéi huò huó dòng.) **(Represents things, actions, or activities that comply with the law.)**

**Option 2: More Explanatory**

* **Description:** 標示與法律效力、權利義務、或符合法律規範相關的文章. 探討合法的定義、法律框架、以及相關議題. (Biāo shì yǔ fǎ lǜ xiào lì, quán lì yì wù, huò fú hé fǎ lǜ guī fàn xiāng guān de wén zhāng. Tàn tǎo hé fǎ de dìng yì, fǎ lǜ kuàng jià, yǐ jí xiāng guān yì tí.) **(Marks articles related to legal validity, rights and obligations, or compliance with legal regulations. Explores the definition of legal, legal frameworks, and related issues.)**

**Option 3: Emphasis on Practical Application**

* **Description:** 此標籤下的文章探討與法律有關的議題，包括合法的商業行為、合法的權益維護、以及避免觸犯法律的方法. (Cǐ biāo qiān xià de wén zhāng tàn tǎo yǔ fǎ lǜ yǒu guān de yì tí, bāo kuò hé fǎ de shāng yè xíng wéi, hé fǎ de quán yì wéi hù, yǐ jí bì miǎn chù fàn fǎ lǜ de fāng fǎ.) **(Articles under this tag discuss legal issues, including legal business practices, the protection of legitimate rights and interests, and ways to avoid breaking the law.)**

**Option 4: Focused on Comparison (If related to other tags)**

* **Description:** 與「非法」相對，本標籤涵蓋所有符合法律規定的內容。 涉及合法的商業活動、權益保障，以及其他法律相關的議題. （Yǔ 『fēi fǎ』xiāng duì, běn biāo qiān hán gài suǒ yǒu fú hé fǎ lǜ guī dìng de nèi róng. She she hé fǎ de shāng yè huó dòng, quán yì bǎo zhàng, yǐ jí qí tā fǎ lǜ xiāng guān de yì tí.） **(In contrast to “Illegal,” this tag covers all content that complies with the law. It addresses legal business activities, the protection of rights and interests, and other legal-related issues.)**

**Choosing the right description:**

* **Context is key:** Consider the subject matter of your blog or website. Does it focus on legal topics? Or is this a more general tag?
* **Target Audience:** Who are you writing for? Are they legal professionals or the general public?
* **Keyword optimization:** While not overly emphasizing keywords in descriptions, think about what search terms people might use to look for this kind of content. “法律,” “權益,” “商業” (law, rights, business) might be relevant.

I recommend reviewing the content tagged with “合法” and the overall direction of your blog when choosing the most appropriate description. The option you select should best serve the purposes of clarity and searchability.
