* **Target Audience:** Consider if you wish to attract users interested in the literal meaning, the artistic aspects or historical applications.
* **SEO:** While less critical for tags than main content, including relevant keywords (like 書寫/shūxiě – writing, 書法/shūfǎ – calligraphy) can help.
* **Brevity:** WordPress tag descriptions are often displayed in a preview or meta area. Keep it reasonably concise.
* **Tone:** Ensure it aligns with your overall blog’s brand and voice.

Choose the option that resonates the most with you and your blog’s purpose! Remember to add the description when creating the tag within your WordPress backend.
