Here are a few options for a WordPress post tag description, along with the reasoning behind them:

**Option 1 (Concise and General):**

> 中學相關文章標籤。涵蓋所有關於中學的討論、新聞、文章、和資源。 (Related posts about junior high/middle school. Covers all discussions, news articles, and resources related to middle school.)

* **Reasoning:** This is a good general description. It clearly explains what the tag is for and is easily understood. The use of “涵蓋” (covers) indicates a broad scope.

**Option 2 (More Specific):**

> 標記關於香港、台灣等地區中學教育、升學、生活、和學生經驗的文章。 (Tag for articles about middle school education, entrance exams, life, and student experiences in regions like Hong Kong and Taiwan.)

* **Reasoning:** This option narrows the focus, hinting at the potential geographical considerations, particularly for those who wish to attract articles about hong kong and taiwan education system for the audience.

**Option 3 (Focusing on Content Types):**

> 標記包含中學教學、課外活動、升學輔導、教師分享等文章。 (Tag for articles including middle school teaching, extracurricular activities, college counseling, and teacher sharing.)

* **Reasoning:** This option highlights specific content that articles might feature and appeal to the teachers and students too.

**How to Use in WordPress:**

1. **Go to your post’s Edit screen.**
2. **In the “Tags” box, type “中學” (without quotes).** You’ll likely see it auto-populate; if not, hit “Enter/Return” to create it.
3. **To add a description:**
* **Some themes** allow you to directly input the descriptions when you create or edit tags. Look for an “Add tag” or “Edit tag” window, it will appear when select or type a Tag.
* **If not:** You might need a plugin to manage the tags. Some plugins like “Yoast SEO” or other SEO plugins may offer options for setting more detailed tag descriptions, improving SEO too. If you are planning on using SEO plugins, just choose the one you like and the setting will be at the section the plugin provides.
* **If you can’t find them:** You can always go to Tag management page by going through “Posts” -> “Tags”

**Choosing the best option:**

Choose the description that best reflects the content *you* intend to tag with “中學.” Consider the target audience and the types of articles you’ll be writing. For example, if your blog focuses primarily on Hong Kong middle school education, Option 2 might be ideal. If you cover a broad range of topics, Option 1 or 3 might be more suitable.
