The Kam people, officially known in China as Dong people. The Kam are thought to be the modern-day descendants of the ancient Liáo (僚) peoples who occupied much of southern China. Kam legends generally maintain that the ancestors of the Kam migrated from the east. According to the migration legends of the Southern Kam people, their ancestors came from Guangzhou, Guangdong and Wuzhou, Guangxi. The Northern Kam maintain that their ancestors fled Zhejiang and Fujian because of locust swarms. Some scholars (mainly Chinese) also believe that the Kam were a branch of the Bai Yue from the first century CE. The Bai Yue inhabited the Yangze River basin after the collapse of the Yue Kingdom around the first century CE which led to the establishment of many small chiefdoms.
