For some, Oryu Market is a place of survival, a cultural base, or a hunting ground for development. The documentary Oryu Market documents 10 years of this traditional market, and it was made by director Choi Jong-ho, who is a documentarist and a media activist for the local radio broadcasting station, Guro FM. Oryu Market broadcasts a radio program named Paper Airplane (which also features in the film), which interviews a couple who has been running a rice cake shop for a long time and acquaintances of the couple to trace their history of struggle against the redevelopment. Oryu Market is a bit different from the ordinary documentaries about gentrification. It mainly focuses on how the traditional market that once led to heyday of the local market area is about to disappear due to the redevelopment project for building apartment buildings. This shows that Oryu Market has a property of essay documentaries that explore the value and nostalgia of vanishing places. In the opening scene, the camera starts from the dark market streets and then captures the market stores turning on lights and brightening up the dead spaces. Choi highlights the history and atmosphere of the space to point out the values of old things that cannot be pushed away for the sake of speed and efficiency. Oryu Market shows the power of observational documentary by paying attention to the issue and tracking down its evolution persistently.
