Here are a few description options for the WordPress post tag “行動” (Hángdòng, Action) in Traditional Chinese, ranging from concise to slightly more descriptive:

**Option 1 (Concise):**

> 關於執行任務、行動的相關内容。 (Guānyú zhíxíng rènwù, hángdòng de xiāngguān nèiróng.)
>
> *Translation: Content related to executing tasks and actions.*

**Option 2 (Slightly more descriptive):**

> 此標籤收錄與具體行動計劃、策略、以及成功執行相關的資訊。 (Cǐ biāoqiān shōulù yǔ jùtǐ hángdòng jìhuà, cèlüè, yǐjí chénggōng zhíxíng xiāngguān de zīxùn.)
>
> *Translation: This tag categorizes information related to specific action plans, strategies, and successful execution.*

**Option 3 (Focus on Practicality):**

> 彙集實際操作、執行方法、克服挑戰，及推進行動的相關資訊。 (Huìjí shíjì cāozuò, zhíxíng fāngfǎ, kèfú tiǎozhàn, jí tuījìn hángdòng de xiāngguān zīxùn.)
>
> *Translation: Gathers information on practical operations, execution methods, overcoming challenges, and advancing actions.*

**Option 4 (Emphasizing the broader concept):**

> 探索有關採取行動、實現目標、克服困難，以及提升效率的相關文章。 (Tànsuǒ yǒuguān cǎiqǔ hángdòng, shíxiàn mùbiāo, kèfú kùnnán, yǐjí tíshēng xiàolǜ de xiāngguān wénzhāng.)
>
> *Translation: Exploring related articles on taking action, achieving goals, overcoming difficulties, and improving efficiency.*

**Recommendations:**

* **Choose the description that best reflects the *type* of posts you’ll be tagging with “行動.”** Are they mostly about task management? Strategy? Motivation?
* **Consider your audience.** A more general audience might benefit from a simpler description (like Option 1 or 2). If your blog is more technical, option 3 or 4 might be a good fit.
* **Keep it relatively short.** WordPress tag descriptions shouldn’t be overly long.

I recommend selecting either option 1 or 2 as a good starting point, and possibly refining the language (e.g., using more specific vocabulary about the topics this tag will cover) if the content later dictates it.
