Donkey burger

Lurou Huoshao is a kind of sandwich commonly eaten in Baoding and Hejian, Hebei Province, China, where it is considered a local specialty, though it may also be found in other parts of China, particularly in Northeastern China. Chopped or shredded donkey meat or offal is placed within a huǒshāo or shao bing, a roasted, semi-flaky bread pocket, and eaten as a snack or as part of a meal. Hejian style typically serves the meat cold in a warm huoshao while Baoding style serves the meat hot; both often include green chili-pepper and coriander leaves. Lurou Huoshao is a popular street food and can also be found on the menus of high-end restaurants.
A well-known saying, especially in Baoding, is "In Heaven there is dragon meat, on Earth there is donkey meat".
Lurou Huoshao has two styles: Baoding style and Hejian style. Baoding style uses round huoshao, while Hejian style uses rectangular huoshao. Also, Baoding style has hot meat, while Hejian style has cold meat.
Luorou Huoshao has been traced to the Ming Dynasty.
