Abstract: The concept that Shanhaiguan was the boundary between Chinese and foreigners did not exist at all among Koreans in the Ming Dynasty,but the concept was greatly strengthened but great political changes during the Ming-Qing Transition. Koreans was surprisingly tolerant and positive towards the natural and humane landscape inside the Pass,but was overly severe and negative towards the landscape outside the Pass in the Qing Dynasty. Interestingly,the cultural distinction between inside the Pass and outside the Pass was reduced day by day while the boundary conception was gradually being strengthened in the Qing Dynasty, even though the resemblance was more than the distinction between inside the Pass and outside the Pass．
