**Choosing the best option:**

Consider these factors when choosing:

* **Target audience:** Who is reading this post tag?
* **Space available:** How much room is there for the description? (WordPress usually allows for a fair amount of description)
* **Keyword optimization:** Which keywords are most important for search (e.g., “教學流程”, “示範教學”, “試教技巧”)? Option 4 is the richest in keywords without being too long.

I recommend Option 2 or Option 4 as they are most descriptive and useful.
