I'm not sure why, but I always like to see the names of familiar American products in unfamiliar languages when I'm overseas.
So here's a picture I thought you might enjoy of three Coca-Cola products in their Chinese variations.
From bottom to top, that's Diet Coke, Coke and Sprite. Diet Coke is often called Coca-Cola Light overseas.
Also, you know on the nutritional label where it lists the amount of caffeine a soft drink has? In China it has the same label, but it calls caffeine "energy."
So a caffeine-free drink here is apparently an energy-free drink as well.
