Here are a few options for a WordPress post tag description, depending on the intended nuance:

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

> 討論「可否」相關議題，涵蓋各種可能性與權衡。 (Discusses issues related to “yes or no,” covering various possibilities and considerations.)

* **Why this works:** It’s direct and clarifies the scope. “各種可能性與權衡” (various possibilities and considerations) also adds depth.

**Option 2 (More Detailed, Emphasizing Agreement/Disagreement):**

> 標記討論「可否」議題的文章，著重於同意與否、贊成或反對，以及相關的決策與選擇。 (Tags articles discussing “yes or no” issues, focusing on agreement and disagreement, pro and con arguments, and related decisions and choices.)

* **Why this works:** Highlights the debate and the heart of the issue (agreement vs. disagreement). The inclusion of “決策與選擇” (decisions and choices) hints at action.

**Option 3 (Focusing on Practical Considerations):**

> 探索「可否」背後的實際考量，包括可行性、風險、益處與成本，以及最終的評估判斷。 (Explores the practical considerations behind “yes or no,” including feasibility, risks, benefits, costs, and the final evaluation.)

* **Why this works:** Useful if the posts target practical analysis, not just general debate, looking at the practical implications of each decision.

**Option 4 (Simplest and Commonly Used):**

> 關於「可否」的討論。（Discussions about “yes or no”.）

* **Why this works:** Short, sweet, and translates the term itself. Good for quick clarification. Suitable for a blog with many posts.

**How to use these in WordPress:**

1. **Go to your WordPress dashboard.**
2. **Navigate to “Posts” > “Tags”.**
3. **Find the “可否” tag in your list, or create it if you haven’t already.**
4. **In the “Description” field for the tag, paste the description you’ve chosen.**
5. **Click “Update” (or “Add New Tag” if creating a new tag).**

Choose the description which best reflects the nature of the content you plan to tag with “可否”. Consider the overall tone and goals of your blog.
