Seng Saekhu had made his fortune through tax farming. Chiang Saekhu/Shinawatra later founded Shinawatra Silks and then moved into finance, construction, and property development. Thaksin's father, Loet, was born in Chiang Mai in 1919 and married Yindi Ramingwong. Yindi's father, Charoen Ramingwong (born: Wang Chuan Cheng), was a Hakka immigrant who married Princess Chanthip na Chiangmai, a minor member of the Lanna (Chiang Mai) royalty. In 1968, Loet Shinawatra entered politics and became an MP for Chiang Mai. Loet Shinawatra quit politics in 1976. He opened a coffee shop, grew oranges and flowers in Chiang Mai's San Kamphaeng District, and opened two cinemas, a gas station, and a car and motorcycle dealership. By the time Thaksin was born, the Shinawatra family was one of the richest and most influential families in Chiang Mai.
