Changjin Lee started his career as an artist in 2008 with his solo exhibition 《Collected water-Collected shape》. From 2008 to 2010, Lee used pictures of fluids to create a figurative sculpture with an organic free-form shape. His interest in transparent materials led Lee to research materials like acryl and resin until 2012. Lee participated in the program hosted by the Busan Cultural Foundation in 2014 and initiated a project titled < Water always finds its own level > where he created a horizontal line with transparent water-filled bottles hanging from the ceiling inside the white building of Sa Sa Art Project in Cambodia. In his solo exhibition 《A little poetic landscape, and a color chart that is not》 in 2019, Lee experimented with different levels of dye concentration for changes in water color. After that exhibition, Lee started a project that resembles the work in salt fields, titled < dye field染田 >, where he poured the water used in the prior exhibition on a canvas, letting it evaporate to create a ‘dye field’. This became how he disposed of the used water produced in the < Water always finds its own level > project. He tried a new work titled < Dead Plants > as an extension of < Water always finds its own level >, raking dead plants out of a pot and hanging them from the ceiling to create a new horizon by positioning them parallel to the ground. In his solo exhibition 《Thunder》(2020), he visualized a lightning with luminous EI wires and nine speakers. Since 2021 he is creating barbed wire entanglements using EI wires of same material used in 《Thunder》.
