The first group of Chinese people to settle in large numbers to escape the coastal ban were the most affected Tanka boat people, other came in much smaller numbers, Teochews from Chaozhou, the Hakkas from Chengxiang county (now renamed Meixian), Huizhou (pronounced Fuizhew in Hakka) and rural county of Dabu (pronounced Thaipo in Hakka), the Cantonese from Guangdong and various different ethnic dialect groups who left the trading city ports of southern Fujian including the ethnic Tanka, Hakkas, etc. Descendants of Hokkien Tanka are the dominant group in eastern Indonesia, Central and East Java and the western coast of Sumatra. Teochews, southern neighbors of the Hokkien, are found throughout the eastern coast of Sumatra, in the Riau Archipelago, and in western Borneo. They were preferred as plantation laborers in Sumatra but have become traders in regions where the Hokkien are not well represented.
