Here are a few options for a WordPress post_tag description, tailored to different needs:

**Option 1: Simple & Descriptive**

* **Title:** 貓尾巴
* **Description:** 關於貓尾巴的一切，包括它們的形狀、功能、以及背後的有趣故事。 探索貓尾巴的世界！ (Everything about cat tails, including their shapes, functions, and interesting stories behind them. Explore the world of cat tails!)

**Option 2: More Engaging & Focused**

* **Title:** 貓尾巴
* **Description:** 想了解貓尾巴的秘密嗎？從尾巴姿態解讀貓的情緒密碼，到各種貓品種的獨特尾巴，這裡有你所需的一切資訊！ (Want to know the secrets of cat tails? From interpreting a cat’s emotions through tail postures, to the unique tails of different cat breeds, here’s everything you need!)

**Option 3: SEO-friendly (using keywords)**

* **Title:** 貓尾巴
* **Description:** 貓尾巴, 貓咪尾巴, 貓咪尾巴的用途, 貓尾巴的語言, 貓咪的健康, 貓尾巴姿勢，貓咪品種。查找關於貓尾巴的最新資訊，了解貓咪的情緒，品種特徵，以及如何照顧你的貓友！ (Cat tails, cat’s tails, uses of cat tails, the language of cat tails, cat’s health, cat tail postures, cat breeds.

**Option 4: Concise & direct**

* **Title:** 貓尾巴
* **Description:** 貓尾巴相關資訊。 (Information related to cat tails.)

**Key Considerations when choosing:**

* **Target Audience:** Who are you writing for? Are they beginners or experienced cat owners?
* **Post Content:** Does your blog post focus on function, emotion, breed, or something else? Match the description to the article’s content.
* **SEO:** Include relevant keywords to help your post rank in search results.
* **Length:** Keep the description within a reasonable length that’s still informative. WordPress doesn’t usually display really long descriptions.

I recommend starting with Option 1 or 2 and then adjusting based on your particular article’s focus. Option 3 is good for SEO but you might want to make it flow better and use it only if it feels natural.
