The Teochew people make up the largest Chinese sub-group in Cambodia and make up about 77% of the Chinese population. About 85% of the Teochews in Cambodia came from the prefectures of Jieyang and Shantou of Guangdong province in China. The earliest records of Teochew immigrants date back to the 16th century when some mutineers under the leadership of the Chinese pirate, Lim To Khieng settled in Cambodia. No significant of Chinese immigration from the Chaoshan region occurred until the 1860s, and the Teochews came to Cambodia in modest numbers in the later part of the 19th century. Large-scale immigration occurred in the 1920s and 1930s, and the Teochews established themselves as the dominant Chinese sub-group thereafter. Approximately 48% of the Teochews live in rural area, and they made up about 90% of the rural Chinese population. The Teochews is also the largest sub-group in Cambodia, where some 100,000 out of 135,000 Chinese in 1962 are from this sub-group. Teochews in rural region of the country generally make their living as village shopkeepers, rural credit moneylenders, rice merchants or as vegetable farmers. In Phnom Penh and the smaller towns, the Teochews are generally import-export Entrepot traders, pharmacists or street peddlars.
