**Tips for Choosing the Right Description:**

* **Audience:** Who is your audience? Are they looking for general information, practical advice, or legal specifics?
* **Content Focus:** Does your blog post mainly focus on forms, procedures, or something else?
* **Length:** Consider the space available in your WordPress theme for the description.
* **Keywords:** While not always explicitly set as a way to improve SEO, including related keywords (like 辭職, 離職信, 勞工權益, 勞資關係) in a description helps to signal the content of the related posts.
* **Consider the Context:** If your site has a specific focus (e.g., legal aspects, employee benefits, etc.), tailor the description accordingly.

Choose the description that best reflects the overall content of your tagged posts and meets the needs of your readers. Always double-check for typos!
