Hi!. Thanks for this great website!. I'm from Argentina and I'm currently studying chinese at UIBE (对外经济贸易大学) in Beijing, and your blog is a very good resource for my 阅读 class (很难！)

In my 口语 class we learned 班长 as "Class monitor". Each class has one.

Keep on updating the blog as much as you can!. Good luck :)
