Taikang County (), formerly known as Yangjia County or Yangxia County, is a county in the north of Zhoukou prefecture-level city, in the east of Henan province, China. It is divided into 23 townships and 766 villages. The county is home to 1.43 million Han Chinese and 25,000 Hui, with a population density of 581 people per kilometre squared. History The administrative area of Taikang was originally known as "Yangxia County"; its name was derived from Xia dynasty king Tai Kang. The character "" is normally pronounced as but in Central Plains Mandarin is pronounced . As a major thoroughfare, the county has been historically important. It was the hometown of Wu Guang, one of the peasant leaders of the rebellion against the Qin dynasty. It was also the ancestral hometown of the Xie and Yuan surnames; it consequently was the birthplace of several famous Xie clan members such as Xie Daoyun, Xie Hui, Xie Lingyun, Xie Tiao, and others. Following the start of the chaotic Sixteen Kingdoms period, Yangxia County initially remained part of the areas held by the Eastern Jin, but was later conquered by the Former Qin. In course of the latter's decline, the county was occupied by the Northern Wei that held it until 446. It was then captured by the Liu Song dynasty, but reconquered by the Northern Wei in 488. Toward the end of the Northern and Southern dynasties period, Yangxia County fell to the Sui dynasty, which changed its name to "Taikang County" in 587. In 884, the Tang army under Li Keyong defeated the rebel army of Shang Rang at Taikang. By time of the Ming dynasty, Taikang had grown rich as trade center and market town, and was widely nicknamed "Silver Taikang". Due to this wealth, however, the town was repeatedly sacked in times of political unrest. It was plundered by the Shun rebel army of Li Zicheng in 1644 during the fall of the Ming dynasty. In course of the Nian Rebellion, Taikang was plundered by insurgents four times, namely in 1852, 1856, 1861, and 1863. After the Xinhai Revolution's outbreak, the Yellow Sand Society and the Cha Tianhua bandit group raided the town in 1911. In the following years, Taikang's economic importance declined due to the construction of railways in the region, but it was still the target of rampaging bandits and soldiers in the Warlord Era and Nanjing
