The Fujian region in many historical records is one the Austronesian migration route region (图12, 图13). Since the Ming Jiajing era until the 1980s, Fujian people built many houses known as tulou. In many variants of Tulou's house, Huang Han Min classified the tulou house into 3 types which are most commonly found: round building, square building and wu feng building. Round building and square building types are divided into inner corridor type and the unit type. Corridor type has a continuous circular corridor that is directly related to the inside, this is what distinguishes it from the round house type unit. The inner corridor type is commonly the houses of Hakka people in the west of Fujian.
