2. **Target Audience:** Are your readers familiar with more complex vocabulary? If so, you might opt for a more detailed explanation. If you’re writing for a broader audience, a simpler description might be better.
3. **SEO (Search Engine Optimization):** Consider some of the above options, depending on how people are likely to search on your site or external search engines.

**How to Add the Tag Description in WordPress:**

1. **In the Tag Edit Screen:** When you’re editing the “罪魁禍首” tag in WordPress (under Posts -> Tags), you should see a field called “Description.” Paste your chosen description into this field.
2. **Save the Tag:** Make sure to save the tag after adding the description. WordPress will often display this description when users view the tag archive page, helping them understand what the tag represents.

I recommend choosing the option that balances clarity, relevance to your content, and the level of detail that suits your audience. Good luck!
