**General Considerations when choosing the best description:**

* **Length:** WordPress allows for moderately long descriptions (around 150-200 characters). Choose the option that best covers the key topics, but also keeps it easily readable.
* **Keywords:** Consider terms people are likely to search for (e.g., “關節炎”, “關節疼痛”, “關節保養”, “類風濕性關節炎”) and include them naturally.
* **Tone:** Choose a tone that is suitable for your blog. Friendly, informative, and supportive are often good choices for health topics.
* **Relevance:** Make sure the description accurately reflects the content you’re tagging (posts related to that topic).
*You can also create variations of these options and test which drives more interactions.*
