The custom of dressing in white must be a fairly ancient one for we learn that at this time the government ordered the use of blue instead of white, as blue is the color that corresponds to east. The birth of a son to the king’s Mongol consort was the signal for great rejoicings and festivities. Everyone offered congratulations, even the discarded queen. It is said that the king paid some attention to this former queen and that it aroused the fierce jealousy of the Mongol queen. She declared that she would write and complain to the emperor that she was being ill treated. She was dissuaded from this by the earnest entreaties of the officials. At the same time a further concession was made to the Mongolizing tendency by changing the names of official grades to those in use among the Mongols. The emperor had not given up his plan of subduing Japan, and for this purpose he began the preparation of boats in the south of Korea, calling upon the Koreans to supply all the requisites. But this was not the only use to which he put his Koryŭ vassal, for he also demanded women and pearls; the former were taken from the men and the latter from the women; and both were sent to the Mongol court. The Mongol queen of Koryŭ was a thrifty woman and let no small scruples stand in the way of the procuring of pin-money. She took a golden pagoda from one of the monasteries and melted it down. The bullion found a ready market. She also went into the ginseng raising business on her own account, taking people’s fields by force and marketed the crop of ginseng in Nanking, where it brought a good price. She thus turned an “honest” penny. But it all went against the aristocratic tendencies of the king. That the queen was not without a touch of superstition is shown by the fact that she desisted from accompanying the king to the grave of Wang-gön when told that the spirit of the founder of the dynasty was a strong one and that if she went she might be attacked by some dangerous disease.
