Here are a few options for the WordPress post_tag description, depending on the nuance you want to convey, all in Traditional Chinese:

**Option 1 (General & Broad):**

* **Description:** 迎接新學期的到來！分享學習、生活點滴，開啟嶄新的篇章。 (Welcome the new semester! Share your learning experiences, daily life, and begin a new chapter.)

**Option 2 (Focus on Excitement & Anticipation):**

* **Description:** 充滿活力的新學期！期待挑戰、結交新朋友，一起創造美好的回憶。 (A vibrant new semester! Looking forward to challenges, making new friends, and creating wonderful memories together.)

**Option 3 (Focus on Practical Aspects):**

* **Description:** 關於新學期的各種討論和資訊，例如課程安排、學習技巧、校園活動等等。 (All kinds of discussions and information about the new semester, such as course schedules, study skills, campus activities, etc.)

**Option 4 (Short & Sweet):**

* **Description:** 全新學期，開始！ (A brand new semester, let’s begin!)

**To choose the best option, consider:**

* **The overall tone of your blog:** Is it generally motivational, informative, or casual?
* **The content you’ll be tagging with this term:** What kinds of posts will you be using this tag for?

Remember to insert the description into the appropriate field when you create the post tag within your WordPress admin panel (e.g., Yoast SEO plugin if installed or via the tag settings). I recommend Option 1 or Option 2 as a great start as they cover general use cases.
