Here are a few options for the description of the WordPress post_tag “增肥” in Traditional Chinese, catering to different levels of detail and potential uses:

**Option 1: Concise & Direct**

* **Description:** 關於增加體重、增胖相關的文章標籤。 (About articles related to gaining weight and bulking up.)

**Option 2: Slightly More Informative**

* **Description:** 涵蓋增肥飲食、運動、營養補充等方面的文章。 透過增肥，建立更健康的體格。 (Covers articles on bulking diets, exercise, and nutritional supplements. Through bulking, building a healthier physique.)

**Option 3: Emphasizing Content Focus**

* **Description:** 此標籤用於標記與增肥策略、食譜、鍛鍊計畫、以及相關健康資訊的文章。 (This tag is used to mark articles related to bulking strategies, recipes, workout plans, and related health information.)

**Option 4: For a Broader Audience (Consider Context)**

* **Description:** 分享如何透過健康的方式增加體重，適合想要增胖、改善體型的人參考。 內容包括飲食建議、運動技巧、以及其他相關的增肥資訊。 (Sharing how to gain weight in a healthy way, suitable for those wanting to bulk up and improve their physique. Content includes dietary advice, exercise techniques, and other relevant bulking information.)

**Key Considerations when Choosing:**

* **Target Audience:** Who is reading your blog/website? This will influence the tone and level of detail.
* **Content Coverage:** What kind of content will use this tag? Make the description reflect the specific topics covered.
* **Search Engine Optimization (SEO):** While tags are not as crucial as they used to be for SEO, consider relevant keywords (e.g., 飲食 (diet), 運動 (exercise), 健康 (health))
* **Brevity:** WordPress likes them short. Keep it under 150 characters for best effect.

**Recommendation:**

I recommend starting with **Option 2 or 3**, as they provide a good balance of information and conciseness. Then, you can refine it based on your actual content. Remember to update the description if your focus changes over time.
