Thank you teachers!

To celebrate World Teachers' Day, we're in the Jiangsu province of China, taking in this bird's-eye view of children drawing together under the tutelage of some hard-working teachers. The UN created this day back in 1994 to draw attention to the vital role that teachers play in providing kids like these with a quality education. It also highlights the obstacles that teachers face every day, particularly in challenging times like these.
