An assortment of different tea bricks displayed in the window of a tea shop in Kunming, China. The round ones are made from pu-erh tea; the square embossed one on the bottom is made from powered black tea. The window display got me to go into the shop, but I spent most of my time inside tasting different delicious oolong teas. I was quite awake when I finally left. [NOTE: The student that took me to this shop purchased a large quantity of tea that she said was for stuffing in your pillow to give you sweet dreams. Nice idea.]
