**Choosing the Best Option:**

* Keep it concise and easy to understand.
* Use keywords that your target audience would likely search for.

You can select the best option for you from the above, or modify it slightly to better suit your needs. Remember to also make the “Slug” (URL-friendly version of the tag) lowercase and use hyphens (e.g., “shijie-shuji”) for better SEO.
