Shenism (the Chinese folk religion or the ethnic religion of Han Chinese, or shen 神 worship) in Southeast Asia plays a dynamic role in the lives of the Chinese populations that have settled in the countries of this geographic region, particularly Burmese Chinese, Singaporean Chinese, Malaysian Chinese, Thai Chinese and Hoa. The Indonesian Chinese, by contrast, were forced to adopt en masse either Buddhism or Christianity in the 1950s and 1960s, abandoning traditional worship, due to Indonesia's religious policies which forbade Chinese traditional religion.
The Chinese folk religion of Southeast Asian Chinese people is markedly typified by the interaction with Malay indigenous religions (Malaysian and Indonesian folk religion) and the adoption of gods of Hindu derivation, such as Brahma, Ganesha and Hanuman. The philosophical forms of Confucianism and Taoism are followed, and organised forms of the Chinese folk faith, such as Dejiao, Yiguandao and Zhenkongism, have taken significant foothold among Southeast Asian Chinese.
