Kang surname originated in Weiguo, and now governs eastern Henan, western Shandong and southwestern Hebei. The early spread of Kang surname was due to Dewey's migration and finally arrived in northern Henan.

During the Wei, Jin, Southern and Northern Dynasties, Gansu Kang moved to Lantian (now the west bank of Xibahe River in Lantian, Shaanxi) to escape the war, and then gradually moved to the southeast.

In the Song Dynasty, Kuang's family, which was changed to avoid the emperor, became a new branch of Kang's surname.
