**Option 1: Concise & Clear (Suitable for general use)**

**Recommendation:**

I recommend **Option 2** or **Option 3** as they provide the most useful information for readers and potentially improve your search engine optimization. Choose the option that best suits your specific website’s style and audience. You can also slightly modify these options to better fit your site’s voice. Remember to also consider using the pinyin romanization (jiàn dìng) in the description for the English version of your website (if applicable).
