**Recommendation:**

I recommend **Option 2** as the best balance between clarity and descriptiveness. It provides a good overview of the content covered by articles tagged with “不動產案件.” However, the best option depends on the specific focus of your WordPress site. If it’s very broad, Option 2 is great. If it’s more focused, Option 1 might be sufficient. Option 3 is good for maximizing keyword usage in a short description.
