**Key Considerations When Choosing a Description:**

* **Target Audience:** Who are you trying to reach? Are they looking for general advice or specific guidance?
* **Content of Your Posts:** What kind of content will be tagged with “選系”? Is it general advice, specific department reviews, personal stories, etc.?
* **Length:** WordPress allows for pretty long tag descriptions, but a concise description is often easier for users to grasp quickly.
* **Keywords:** While the title is already “選系,” consider adding relevant keywords within the description to help with search engine optimization (SEO). For example, you could include words like “升學” (college entrance), “大學” (university), “科系介紹” (department introduction), “生涯規劃” (career planning), or specific fields of study.

Choose the option that best reflects the overall content and goals of the posts tagged with “選系.” Good luck!
