In the Korean era (1392-1910), the Rensi Cave was a densely populated area of government and two classes of private houses. Since the late period of Japanese occupation of Korea, the two classes of Rensi Cave, which had fallen down, took out their household goods and sold them for money. As a result, some antique shops have emerged here as the times require. Later, Rensi Tung Antique Street had galleries for exhibiting and selling antiques and related shops, and Rensi Tung gradually became a cultural street for buying and selling cultural commodities. Generally speaking, Rensi Cave refers to the area that passes through Rensi Cave intersection from Anguo Cave Circle Island to the front of Tagu Park on 2nd Street of Zhonglu. Rensi Cave is centered on the Central Street, surrounded by many alleys, many and dense, like spider webs. There are many famous places of Rensi Cave hidden in Hutong.
