**Option 1: Concise and General**

**Choosing the Best Option:**

* **Consider your audience:** Who are you writing for? Are they primarily Chinese speakers, or are you also targeting English-speaking readers?
* **The content of your posts:** What types of posts will you be tagging with “習俗”? Will you focus on specific festivals, general cultural practices, or both?
* **Your SEO goals:** If you’re concerned with search engine optimization, include relevant keywords (e.g., specific holidays, actions, or items related to customs).
