One of these pictures is Lijiang decorated for Chinese New Year (Spring Festival). Red is the color of choice and balls are the shape of choice and they're everywhere! And this is the time of year that fireworks are going off 24/day. Americans typically enjoy the ones that are colorful and big things to see. Chinese prefer the louder ones! And the other two pictures are of meat hanging, obviously. This is how they sell meal all over the country. They want you to be able to see what you're buying:) One of the pictures if of Duck. You can see the beaks!
