**Key considerations when choosing a description:**

* **Your Audience:** Who is reading your blog? Are they mostly Chinese speakers? What is their age range and cultural background?

* **Your Comfort Level:** Are you comfortable being explicit?

**How to use these in WordPress:**

1. **Go to your WordPress admin panel.**
