The important matter of revenue received early attention. A novel method was adopted. All arable land was divided into squares and each square was subdivided into nine equal parts; eight squares about a central one. Whoever cultivated the eight surrounding squares must also cultivate the central one for the benefit of the government. The latter therefore received a ninth part of the produce of the land. Prosperity was seen on every side and the people called the Ta-dong River the Yellow River of Korea. As a sign that his kingdom was founded in peace and as a constant reminder to his people he planted a long line of willows along the bank of the river opposite the city, so P‘yung-yang is sometimes called The Willow Capital. It is contended by not a few that Ki-ja never came to Korea at all and they base their belief upon the following facts. When the Han Emperor Mu-je overcame northern Korea and divided it into four parts he called the people savages, which could not be if Ki-ja civilized them. The Chinese histories of the Tang dynasty affirm that Ki-ja’s kingdom was in Liao-tung. The histories of the Kin dynasty and the Yuan or Mongol dynasty say that Ki-ja had his capital at Kwang-nyŭng in Liao-tung, and there is a Ki-ja well there today and a shrine to him. There was a picture of him there but it was burned in the days of Emperor Se-jong of the Ming dynasty. A Korean work entitled Sok-mun Heun-t’ong-go says that Ki-ja’s capital was at Ham-pyŭng-no in Liao-tung. The Chinese work Il-t’ong-ji of the time of the Ming dynasty says that the scholars of Liao-tung compiled a work called Söng-gyŭng-ji which treated of this question. That book said that Cho-sŭn included Sim-yang (Muk-den), Pong-ch’ŭn-bu, Eui-ju and Kwang-nyŭng; so that half of Liao-tung belonged to Cho-sun. The work entitled Kang-mok says that his capital was at P’yŭng-yang and that the kingdom gradually broadened until the scholar O Si-un said of it that it stretched from the Liao River to the Han. This last is the commonly accepted theory and so far as Korean evidence goes there seems to be little room for doubt. Ki-ja was fifty-three years old when he came to Korea and he reigned here forty years. His grave may be seen to-day at To-san near the city which was the scene of his labors. Some other places that claim the honor of containing Ki-ja’s tomb are Mong-hyŭn, Pak-sung and Sang-gu-hyun in northern China. It was not till thirty-six generations later that Ki-ja received the posthumous title of T’ă-jo Mun-sŭng Tă-wang. The details of the history of K-ja’s dynasty are very meager and can be given here only in the most condensed form.[A] Footnote A:
