The second China Donkey Burger Festival kicked off in Hejian, Hebei province, April 28.

Donkey burger, also known as lvrou huoshao, is a snack where sliced donkey meat is stuffed inside a baked wheat bun. Hejian, located 200 kilometers south of Beijing, is widely considered to be one two possible birthplaces of the Chinese donkey burger, the other one being Baoding, also in Hebei province.

The skill of cooking Chinese donkey burger was officially listed as Hebei province's intangible cultural heritage in June 2011, while the China Hotel Association certified Hejian as the "home of Chinese donkey burger" in April last year.
