What are the characteristics of Korean folk houses?

Korean culture is more influenced by the Han nationality, so the general pattern of its folk houses is similar to that of the Han nationality. There are two kinds of plane layout: symmetric and asymmetric (multi-asymmetric in rural areas). Because of the cold climate in winter, kang is often used to keep warm in the house. Most houses are just rectangular houses with four or five rooms, and some have porches. There are two kinds of roofs: grass roofs and tile roofs. The tile roof is more elegant, and it is often made to rest at the top of the mountain, which is more beautiful. Because there is a burning kang, there are tall chimneys near almost every home.
