Consider these factors when selecting the best option:

* **Length:** WordPress tag descriptions are generally kept short.
* **Website Content:** What is the overall theme of your website? Is it focused on mental health, work-life balance, literature, etc.? Choose a description that complements your content.
* **Specificity:** Do you want a general description or something specific to the types of posts tagged with “倦怠”?

You can also modify the wording a bit if you want. For example, you could replace 舒緩情绪 (shūhuǎn qíngxù – alleviate emotions) with something more specific like “提高活力，增加動力” (tígāo huólì, zēngjiā dònglì – increase energy and drive).
