Commissioned for “Liquid Ground,” an exhibition curated by Alvin Li and Junyuan Feng, Lee Kai Chung’s installation Sea-sand Home (2021) lays bare the tensions between people, nation-states, and the environment. At its core are research materials from Lee’s investigation into the Guangxi origins of the sand that has been used to extend the coast of Hong Kong’s Lantau Island as part of the multi- billion-dollar “Lantau Tomorrow Vision” infrastructure project. The integration of mainland Chinese soil into the ground of Hong Kong draws a vivid metaphorical image of the complicated geopolitics between the two places, evoking the inevitable total reclamation of the Special Administrative Region by the mainland.
