**Option 4: (More Formal)**

**Which to choose?**

Remember to choose the description that best suits your blog’s overall style and the type of content you expect to tag with “幾天.” You can also tailor any of these suggestions to be even more specific to your needs. For example, if your blog is about travel, you could modify any of these options to include the word “旅行” (travel) more explicitly.
