Uncle Wei Kang, the ninth son of King Wen, the younger brother of King Wu, the first monarch of the State of Wei, after king Wu destroyed the Shang, because uncle Kang was young, he did not seal the country for the time being. After the death of King Wu of Zhou, King Cheng of Zhou ascended the throne at a young age, and although the Zhou Dynasty had been established, the political situation was not very stable, and the remnants of Dongyi and Yin Shang were not completely submissive, and King Wu's younger brother, King Cheng's uncle Zhou Gongdan, then became involved in the government of the country, acting as King Cheng of Zhou and handling major state affairs. This caused the dissatisfaction of Guan Shuxian and Cai Shudu, who were far away in the town of Yin Shang' hometown, and suspected that Zhou Gongdan was suspected of usurping the throne, and the two were indignant in their hearts, spreading rumors everywhere to slander Zhou Gongdan. In the second year of becoming king, Uncle Guan and Uncle Cai launched a rebellion against Wu Geng, the son of King Shang, and on the other hand, they joined forces with the states of Huaiyi, Xu Rong, Xiang, and Pugu to launch a rebellion. Uncle Kang was the first to receive news of Wu Geng's rebellion, and while deploying troops to prevent the rebels from invading, he sent people to rush to Wang Du Haojing to report the news of Wu Geng's rebellion.
In the fourth year of King Cheng of Zhou, Zhou Gongdan marched east in the name of King Cheng, and with the assistance of Taigong Wang and Zhao Gongyi, it took three years to quell the rebellion, killing Wu Geng, Guan Shuxian, and exiled Cai Shudu. During this period, Uncle Kang also participated in this military operation, and in the process of counterinsurgency, Uncle Kang gradually grew, so his brother Zhou Gongdan decided to divide the area ruled by Wu Geng into two, part of which was awarded to King Huan's younger brother WeiZikai to establish the State of Song, and part of the reward to Uncle Kang, who had made meritorious contributions to the counter-rebellion, and establish the Wei State.
When Uncle Kang went to office, his brother Zhou Gongdan was worried that Uncle Kang would not be able to properly manage the old land of Yin Shang when he was young, and repeatedly warned Uncle Kang that he must forgive the punishment of Mingde, love the people, and ask those talented, prestigious, and experienced sages and elders in Yin Shang's hometown about the way for Yin Shang to rise and fall. He also warned Uncle Kang that the reason why the king of Lu fell to the country was because he was indulging in wine and indulging in female color, so Uncle Kang must abstain from alcohol.
After Uncle Kang took office, he respectfully obeyed the teachings of his elder brother, took the "Zi Cai" as the law of governing the country, was diligent in government affairs, cared for and respected subordinate officials; Mingde lenient punishment and appeased people's hearts; observed the people's feelings, cared for and loved the people; attached importance to the selection of talents, listened to the advice of the sages, and worked hard to implement moral government. Under the administration of Uncle Kang, the economy of Weiguo has developed rapidly, the society has been stable, and the people have settled down.
After King Cheng of Zhou took charge of state affairs, in view of Uncle Kang's good governance and outstanding political achievements, he promoted Uncle Kang to the post of Western Zhou Sikou and was in charge of criminal prisons, litigation and other affairs. Uncle Kang enforced the law impartially and successfully maintained the stability of the Western Zhou regime. In recognition of Uncle Kang's virtue, King Zhou Cheng gave Uncle Kang many treasures and sacrifices. After Uncle Kang's death, his son Wei Kangbo succeeded to the throne.
