Here are a few options for the WordPress post tag description, catering to different needs and lengths. Choose the one that best suits your overall SEO strategy and website’s tone:

**Key Considerations:**

* **Keywords:** Ensure the description incorporates important keywords like “骨骼肌疼痛” (musculoskeletal pain), “原因” (causes), “症狀” (symptoms), “治療” (treatment), “預防” (prevention), “肌肉” (muscle), “關節” (joint), etc.
* **Target Audience:** Consider who you’re writing for. Are you targeting a general audience, or a more medically informed one?
* **Content Focus:** Align the description with the *actual content* of your posts tagged with “骨骼肌疼痛”.
* **Character Limit:** WordPress might have character limits for tag descriptions. Keep that in mind.

**Recommendation:**

I recommend **Option 1 or Option 2** in most cases. Option 1 is straightforward and good for SEO. Option 2 is slightly more user-friendly and highlights the content’s benefits. Choose the option that best fits your overall content strategy and website’s style. Ensure you review your WordPress theme’s settings to find where to add the tag description; it is not always obvious. Good luck!
