**Key Considerations When Choosing:**

* **Keyword Optimization:** Consider including relevant keywords (e.g., 離別, 道別, 分別) in your description to aid search optimization, but don’t stuff the description with them.
* **Clarity & Conciseness:** Make sure the description is easy to understand and clarifies what content belongs to this tag.
* **Target Audience:** Determine who is most likely to be reading your post and use language that resonates with them.

I recommend starting with Option 1 or 2 and tailoring it to fit your specific needs. Remember to use your own words and style if possible, because it’ll sound more natural.
