The influence of foreign culture is often reflected in the form of settlements, and some of that influence appears to be significant, as is the case of the Majianglong Villages, China. To understand the current form of the vernacular buildings in Majianglong Villages, this research has traced its typological process. It is found that the Western-style vernacular buildings inherited the local traditional plan, Sanjianlianglang. The hierarchy of morphological changes under the influence of foreign culture is also examined. The lower levels of the hierarchy such as materials and structures were influenced greatly, while higher levels such as the organization of the buildings and the villages still followed traditional form, in accordance respectively with the family structure and clan structure reflecting local culture. The Sanjianlianglang plan, the scale of the site and finally the plot arrangement, combine to create the hierarchy of the morphological frame, which seems to be stable and unlikely to change.
