Although Thailand is well-known for its success in acculturating and assimilating its Chinese population, some scholars have suggested that these acculturated Chinese have not become fully Thai culturally, but have developed distinct and separate Sino-Thai worldviews. Based on research in Chiang Mai, this paper considers the degree to which Thai and Sino-Thai partake in the same worldviews, and suggests that high status Chinese females play a pivotal role in the acculturation of their families and others in the Chinese community, and in the transmission of a more traditional Thai worldview.
