**How to choose:**

* **Consider the post content:** Does the majority of the content focus on the experience of not sleeping, the causes, the solutions, or a combination of these?
* **Keep SEO in mind:** Use relevant keywords related to *失眠* (shīmián – insomnia), *睡眠* (shuìmián – sleep), and *改善* (gǎishàn – improve) if appropriate for your target audience.
* **Be clear and concise:** The description should quickly convey what the tag is about.

Remember to choose the option that best reflects the content of the posts tagged with “輾轉難眠.” I recommend `Option 1` or `Option 2` as they are most comprehensive and actionable. Also, be consistent with your description style for better organization in your WordPress site.
