Ten years ago, I traveled to the United States for the first time with more than 30 classmates and professors from the EMBA program. Our first stop was Chicago.

Ten years later, returning to the same place, countless memories flooded back. Chicago still feels young, but the youth has turned into maturity!

By the way, Chicago is very nice. The price of five-star hotels is half of New York, and dining is also half. The key is that it's cleaner and tidier than New York!
