Here are a few options for WordPress post tag descriptions, considering varying levels of detail and focus, all in Traditional Chinese:

**Option 1: Concise and General**

* **描述:** 網站顯示問題的標籤。 (Tags related to display issues on the website.)

**Option 2: More Specific & Helpful**

* **描述:** 標記與網頁錯誤、連結失效，或其他網站功能異常相關的文章。 包含404錯誤、伺服器錯誤等。 （Tags articles related to web errors, broken links, or other website malfunctions. Includes 404 errors, server errors, etc.)

**Option 3: Emphasizing Troubleshooting**

* **描述:** 標記與網站錯誤排除、解決問題，以及改善使用者體驗相關的文章。 (Tags articles related to website error troubleshooting, problem-solving, and improving the user experience.)

**Option 4: Focusing on Types of Errors**

* **描述:** 處理網頁錯誤的分類標籤，例如 HTTP 錯誤、JavaScript 錯誤、CSS 錯誤等。 (Categorizes tags related to web errors, such as HTTP errors, JavaScript errors, CSS errors, etc.)

**Choosing the right description depends on the overall goals of the website.** If you’re just aiming for quick categorisation, option 1 is great. If you’re trying to help users troubleshoot, #3 is excellent. The other provide more granular information.

Ultimately, consider the following:

* **Who is your target audience?** Are they technical users, or general website visitors?
* **What kind of content will be tagged with this?** Will it be detailed technical explanations, or more general advice?
* **What do you want users to do with this tag?** Just read articles, or hopefully try to fix something they encountered?

The descriptions above are designed to be friendly to both Mandarin and Cantonese readers, as the use of “網頁” (website) or “網站” (website) and “錯誤” (error) is universal amongst the two groups.
