In 1650, all kisaeng were made slaves of the government. The kisaeng attached to a government office were known as "gwan-gi", or "kisaeng of the office." Their role did not, by law, include sexual service to the officeholder; in fact, government officials could be punished severely for consorting with a kisaeng. However, in practice kisaeng were often forced to serve the officeholder. A distinction was sometimes made between those "gwan-gi" who were obliged to sleep with the officeholder, and those who were not. This distinction was featured in the popular lay "Chunhyangga".
