The Hoklo people are a Han Chinese subgroup who speak Hokkien, a Southern Min language, or trace their ancestry to southeastern Fujian in China, and known by various related terms such as Banlam people, Minnan people, or more commonly in Southeast Asia as the Hokkien people. The Hokkien people are found in significant numbers in mainland China, Taiwan, Singapore, Malaysia, Philippines, Indonesia, Brunei, Myanmar, the United States, Hong Kong, and Macau. The Hokkien people have a distinct culture and architecture, including Hokkien shrines and temples with tilted sharp eaves, high and slanted top roofs, and finely detailed decorative inlays of wood and porcelain. The Hokkien language, which includes Taiwanese Hokkien, is the mainstream Southern Min, which is partially mutually intelligible to the Teochew language, Hainanese, Leizhou Min, and Haklau Min.
