Dong'an chicken is a Chinese cold parboiled chicken dish, flavoured with chili peppers, ground Sichuan peppercorns, white rice vinegar, scallions and ginger. It is named after Dong'an County. Dong'an chicken is a traditional Hunan dish, which started in the Tang dynasty. In February 1972, when then-U.S. President Richard Nixon visited China, Mao Zedong entertained Nixon with Hunan dishes such as Dong'an chicken at a banquet. It has evolved through three dynasties, named "mature vinegar chicken" in the Western Jin dynasty, "Guanbao chicken" in the late Qing dynasty, and "Dong'an chicken" in the Republic of China.
