Shi Lang (1621–1696), Marquis Jinghai, also known as Secoe or Sego, was a Chinese admiral who served under the Ming and Qing dynasties in the 17th century. He was the commander-in-chief of the Qing fleets which destroyed the power of Zheng Chenggong's descendants in the 1660s, and led the conquest of the Zheng family's Kingdom of Tungning in Taiwan in 1683. Shi later governed part of Taiwan as a marquis. Early life and career Shi Lang was born to a distinguished lineage in Fujian, in 1621. He studied military strategy in his youth, and became particularly proficient in naval warfare. He was also famous for his strength, ferocity and martial skills in battle. Kangxi Emperor once described him as a fierce warrior who was also highly adept in military command skills, however, he was a blunt and rude person who lacked basic manners and courtesy. After fighting a number of minor operations locally with his father, he joined Zheng Zhilong's naval fleet as captain of the left vanguard. Shi Lang served most of the early 1640s in the Zheng family's fleet, where he apparently saw some conflict with Zheng Zhilong's son Zheng Chenggong. When Shi defected to the Qing dynasty in 1646, Zheng Chenggong killed Shi's father, brother and son. Campaign against the Zheng family The Qing rulers prized Shi Lang for his extensive naval experience and his network of contacts in the major trading ports of East Asia. He accompanied Prince Jidu (son of Jirgalang) on an expedition in Fujian in 1656, and attained the rank of Assistant Brigadier-General. In the campaign of 1663 against the Zheng family, he commanded Dutch ships and men to follow up the Qing victories. In 1668, he submitted a plan to drive the remnants of the Ming dynasty from Taiwan and the Pescadores (Penghu), but the proposal was not utilised. He was given a post in the Imperial Bodyguard and attached to the Chinese Bordered Yellow Banner. Conquest of Taiwan In 1681, following the Revolt of the Three Feudatories, the Kangxi Emperor sought a possible leader for an amphibious operation against Taiwan. Following the advice of Li Guangdi, he chose Shi Lang. Shi Lang insisted on having an independent command, not one shared with Yao Qisheng, the Governor-General of Fujian. On 8 July 1683, after extensive preparation, Shi Lang led a force of 300 warships and 20,000 soldiers out of Tongshan, Fujian. On
