Beijing's traditional snack foods are irresistible to visitors to the Chinese capital. Their names alone are enough to entice the curious diner, with local specialties including, ludagun (驢打滾donkey roll about), wandouhuang (豌豆黃pea yellow), aiwowo (艾窩窩), tang'erduo (糖耳朵sugar ear), and hama tumi (蛤蟆吐蜜toad spit honey). Some of these snack foods have existed for 600 years. [Photo by Liu Yi]
