The cultural exchange was also bilateral and Goryeo had significant cultural influence on the Mongols court of the Yuan dynasty (1279–1368); one example is the influence of Goryeo women's hanbok on the attire of aristocrats, queens, and concubines of the Mongol court which occurred in the capital city, Dadu. However, this influence on the Mongol court clothing mainly occurred in the last years of the Yuan dynasty. Throughout the Yuan dynasty, many people from Goryeo were forced to move into the Yuan; most of them were "kongnyo" (literally translated as "tribute women"), eunuchs, and war prisoners. About 2000 women from Goryeo were sent to Yuan as "kongnyo" against their will. Although women from Goryeo were considered very beautiful and good servants, most of them lived in unfortunate situations, marked by hard labour and sexual abuse. However, this fate was not reserved to all of them; and one Goryeo woman became the last Empress of the Yuan dynasty; this was Empress Gi who was elevated as empress in 1365. Most of the cultural influence that Goryeo exerted on the upper class of the Yuan dynasty occurred when Empress Gi came into power as empress and started to recruit many Goryeo women as court maids. The influence of Goryeo on the Mongol court's clothing during the Yuan dynasty was dubbed as "Goryeoyang" ("the Goryeo style") and was rhapsodized by the Late Yuan dynasty poet, Zhang Xu, in the form of a short banbi (半臂) with square collar (方領). However, so far, the modern interpretation on the appearance of Mongol royal women's clothing influenced by Goryeo is based on authors' suggestions. Similarly, the possibility that remains of g"oryeoyang" influence on the Ming dynasty clothing in China is based on speculations and need to be studied further.
