The history of Rensi Cave can be traced back to the late period of Japanese occupation of Korea, when the declining nobles of the government who lived here took out their household goods and sold them for money, so some antique shops came into being here as the times require. Later, there were galleries for exhibiting and selling antiques and related shops in this antique street, and Rensi Cave gradually became an ancient cultural commercial street in Korea. Nowadays, in the bustling downtown area of Seoul, it still retains the original flavor of Korean ancient commercial street. The shops here have both ancient and modern art works, clothing supplies and ceramics, as well as painting and calligraphy plaques and various arts and crafts. The tour guide gave us an hour of free time, and we wandered aimlessly around Rensi Cave Commercial Street under the clouds after the rain. The biggest feature of the block here is that there are many hutongs scattered, dense but not disorderly, quiet and quiet, and these distinctive hutongs are hidden in many restaurants and teahouses that retain Korean style and sentiment, and of course, cafes that modern people like. Perhaps because it's not the weekend, the popularity here is not strong enough. At the entrance of a hutong, a European and American man is playing violin hard. Many Korean women will respectfully place Korean coins in the box under his feet when they pass by. It's a little bit beautiful to cherish heroes. The gallery is also the most common commercial form in Rensidong Commercial Street. It is said that there are hundreds of galleries gathered here. Tourists can enjoy Korean paintings, plate paintings, sculptures and other exhibitions. We saw plaques in Chinese "seeking truth from facts" and "wind, sunshine, plum blossom, Duling fragrance" on the doorway of an art gallery.
