Description

Issue #2058

This is my first contribution to the project.  
I’ve corrected a typo in the Chinese routing guide where the routes `/random.text` and `/` were mislabeled.  

File updated:  
- `guide/routing.md` (Chinese version)

Please review and let me know if any improvements are needed.

I don’t speak Chinese, but I reviewed the diff and the changes make sense based on the code examples. Thanks for the fix @dhruvinjs! 👍
