**Choosing the best option:**

* **Consider your audience:** Who are you trying to reach with this tag? Parents, volunteers, social workers, etc.?
* **Context of your blog:** What is the overarching theme of your WordPress site? Is it practical advice, advocacy, sharing personal stories, etc.?
* **SEO:** Think about keywords that people might search for. Include relevant terms like “寄養家庭,” “費用,” “補助,” “津貼” (subsidy/allowance), “開支” (expenses).
* **Clarity:** Make sure the description is easy to understand.
* **Length**: WordPress suggests a length that is not verbose.

You can adjust these options to best fit your needs. If you’re writing a blog post about specific costs, Option 5 would likely be most effective. Otherwise, Option 1 or 2 are a good starting point. I recommend adding the link. Good luck!
