Yu Gong
One may notice that the name of Qingjun's map "Hunyi Jiangli Tu" (混一疆理圖) bears a striking resemblance to that of the Kangnido, "Hunyi Jiangli Lidai Guodu Zhi Tu" (混一疆理歷代國都之圖) in Chinese. Actually, it is a combination of phrases common during the Mongol era. There were many preceding Chinese maps with similar titles, including the "Yu Gong Jiuzhou Lidai Diwang Guodu Dili Tu" (禹貢九州歷代帝王國都地理圖; Map of Capitals of Historical Emperors and Kings in the Nine Provinces of the "Yu Gong").
