As the educational function of Confucian school in the late Chosun dynasty had been declined, the other educational institution called YANGSAJAE was established. The founders of the institution was either local authorities or local Confucianists. Otherwise the institution was established by the cooperation of both local authorities and local Confucianists. YANGSAJAE began to be established from the 16th century. Most of them was founded in 1700s. In 1800s, it was not so difficult to see YANGSAJAE in many towns in Young nam and Honam provinces. The institution was located in separate places at the early stage of foundation. But since the middle of 1700s, the institution was located in or near the Confucian school. As a consequence, this influenced the location of Confucian schools in the late Chosun dynasty. In Youngnam province, the institution was mainly located near the Confucian school or in a separate place. On the contrary, most of the institution were constructed within Confucian school in Honam province. There were two types of the flat composition: one is based on hall and the other is based on room. The hall type, which had a hall in the middle and rooms in both sides, was general. The hall type usually had a size of 4-kan in width and 1.5-kan in length. The half-hipped roof was the general type and intimately related to the roof of Myung-Ryun Dang of local Confucian School.
