Q: Question: Which of the Chinese folk religions in Thailand is the largest? Passage 1:There is no official state religion in the Thai constitution, which guarantees religious freedom for all Thai citizens, though the king is required by law to be a Theravada Buddhist. The main religion practised in Thailand is Buddhism, but there is a strong undercurrent of Hinduism with a class of brahmins having sacerdotal functions. The large Thai Chinese population also practises Chinese folk religions, including Taoism. The Chinese religious movement Yiguandao (Thai: Anuttharatham) spread to Thailand in the 1970s and it has grown so much in recent decades to come into conflict with Buddhism; in 2009, it was reported that each year 200,000 Thais convert to the religion. Many other people, especially among the Isan ethnic group, practise Tai folk religions. A significant Muslim population, mostly constituted by Thai Malays, is present especially in the southern regions.
