**Key Considerations when choosing:**

* **Your Website’s Focus:** What kind of content do you publish? Is it news, legal analysis, opinion pieces, case studies, etc.?
* **Target Audience:** Who are you writing for? Adjust the language (e.g. more formal for academics, simpler for a general audience).
* **SEO:** Use keywords that people are likely to search for. Consider adding related words like “犯罪,” “違法,” “刑事,” etc. in the description if relevant to your content.
* **WordPress Setup:** Some WordPress themes use Tag Descriptions more visibly than others. Make sure the description will actually be displayed on your site, as it’s used for SEO.

Choose the description that best fits your website’s purpose and target audience. Make sure to save the description after you enter it into the WordPress tag settings!
