Giyesu (; 1645–1697), formally known as Prince Kang, was a Manchu prince and general of the Qing dynasty. Born into the imperial Aisin Gioro clan, he was a distant cousin of the Kangxi Emperor and is best known for leading Qing forces to suppress a rebellion by Geng Jingzhong in southwestern China between 1674 and 1675 and repel an invasion by Taiwan warlord Zheng Jing in 1676–1677.

Title inheritance
Giyesu was born in the Manchu Aisin Gioro clan as a great-grandson of Nurhaci, the founder of the Qing dynasty. His grandfather, Daišan, was the founding title holder of the Prince Li peerage. His father, Hūse (祜塞; d. 1646), who was the eighth and youngest son of Daišan, held the title of a feng'en zhenguo gong or first-class imperial duke. After Hūse died, his title was inherited by his second son, Jinggi (精濟; 1644–1649), who, sometime before 1649, was promoted to a junwang (second-rank prince). Jinggi died in July 1649. Giyesu, who was then only four years old, became the heir to Jinggi's princely peerage. In 1651, he was conferred the title "Prince Kang of the Second Rank".

In 1659, Giyesu's uncle, Mandahai (滿達海), was posthumously convicted and demoted from a qinwang (first-rank prince) to a beile (third-rank prince). Mandahai's son, Chang'adai, was also demoted from a qinwang to beile. The Prince Li peerage, which was previously held by Mandahai, was then passed on to Giyesu, who inherited it under the Prince Kang title; Giyesu was promoted to "Prince Kang of the First Rank".

Career
In the late spring of 1674, Prince Kang was appointed as a general and ordered to lead imperial troops to Zhejiang to suppress a rebellion by Geng Jingzhong, one of the "Three Feudatories". Among his deputies were Fulata, Laita (賴塔), Laha (喇哈) and Jirtab (紀爾他布). In the ninth month, when Prince Kang and his army arrived in Jinhua, Geng Jingzhong had already conquered Wenzhou, Chuzhou and other cities in southern Zhejiang. Not long later, Geng Jingzhong's subordinate, Xu Shangchao (徐尚朝), led 50,000 troops to attack Jinhua. In response, Prince Kang ordered Bayar (巴雅爾) and Mahada (馬哈達) to lead imperial forces to resist the rebels; Bayar and Mahada's forces defeated Wu Rongxian (吳榮先) and killed over 20,000 rebels. In the 12th month, Xu Shangchao personally led 50,000 troops to attack the villages south of Jinhua. Baya'er and Chen Shikai (陳世凱) led imperial troops to attack the rebels and defeated them at Jidaoshan (積道山), and recaptured Yongkang and Jinyun counties from the rebels. Prince Kang defeated Fang Maogong (方懋功) at Shangyu, and Feng Gongfu (馮公輔) at Yiwu and Wuyi County and took back the territories from the rebels.

In 1675, Mahada and Li Rong (李榮) defeated Sha Youxiang (沙有祥) at Taohua Ridge (桃花嶺) and recaptured Chuzhou from the rebels. In the following year, Prince Kang led imperial forces through Zhejiang and prepared to attack Fujian, which was under rebel control. Around the time, Zheng Jing, the ruler of the Kingdom of Tungning in Taiwan, had occupied the prefectures of Zhangzhou and Quanzhou in Fujian. At this point, Geng Jingzhong's rebel forces were running short on supplies. In the ninth lunar month of 1676, Prince Kang successfully recaptured Jianyang and forced the rebels at Jianning and Yanping to surrender. Sensing that defeat was imminent, Geng Jingzhong sent his son, Geng Xianzuo (耿顯祚), to meet Prince Kang and convey his wish to surrender. He personally surrendered to Prince Kang later on. In the tenth month, Prince Kang and Qing imperial forces entered Fuzhou and completely pacified Geng Jingzhong's rebellion.

In the tenth lunar month of 1676, Zheng Jing's subordinate, Xu Yao (許耀), led 30,000 troops to attack Fuzhou. In response, Prince Kang ordered Lahada (拉哈達) to lead imperial forces to resist Zheng's forces. The imperial army was victorious and recaptured Ninghua, Qingliu, Changting and other counties. In the first month of 1677, Lahada and Laita (賴塔) defeated Zheng Jing's forces at Baimaoshan (白茅山) and Taipingshan (太平山), and recaptured Xinghua (now part of Putian and Xianyou) from the enemy. By the second month, they had driven Zheng Jing's forces out of Quanzhou and Zhangzhou and pacified most of Fujian. In the fourth month, Prince Kang wrote to Zheng Jing, who had retreated to Xiamen, to surrender. Zheng Jing refused, so Prince Kang prepared for an attack on Xiamen. At the same time, Prince Kang also recommended Yao Qisheng to the Qing imperial court to serve as the governor-general of Fujian. By 1680, Zheng Jing had been completely defeated in Fujian and forced to retreat with his remaining forces back to Taiwan.

Prince Kang died in 1697 and was posthumously honoured as Prince Kangliang of the First Rank (康良親王). He was survived by at least two sons, Chuntai (椿泰; d. 1709) and Bartu (巴爾圖; d. 1753), who successively inherited the Prince Kang title from their father.
