The distinctive costume of Korean administrators or state functionairs was imported into Korean from Tang China during the Shilla period. The characteristic white-colored clothes of the common people earned them the name paekui minjok or white folk. The upper class woman wore changot or a kind of long hood to maintain her modesty and a long skirt and other items to conceal her head and cheeks from outsiders. Before marriage both boys and girls wore their hair long but when they became adults the men would tie them their hair in a topknot and the women wore their hair in various chignon. Distinctive shoes made of straw, hemp or leather, etc. distinguished the social position.
Rice cultivation is at the center of Korean agriculture.
It has a very long history in Korea and it has been confirmed that it had been practiced in Korea for more than 3,000 years in the Yongsan River basin. The traditional Korean forked plow or ttabi was used as early as the Bronze Age. It is still used even now to cultivate small and narrow farming plots on islands in the southwestern sea. The plow called chaengi was introduced to work open fields from early on and they could be cultivated more easily with the help of domesticated oxen. The chaengi was used in rice paddies while the kukchaengi broke the soil in field.
