Old Trees, Level Distance compares closely in brushwork and forms to Early Spring, Guo Xi's masterpiece dated 1072, in the National Palace Museum, Taibei. In both paintings, landscape forms simultaneously emerge from and recede into a dense, moisture-laden atmosphere: rocks and distant mountains are suggested by outlines, texture strokes, and ink washes that run into each other to create an impression of wet, blurry surfaces. Guo Xi describes his technique in his painting treatise: "After the outlines are made clear by dark ink strokes, use ink wash mixed with blue to retrace these outlines repeatedly so that, even if the ink outlines are clear, they appear always as if they had just come out of the mist and dew" (Linquan gaozhi [Lofty Ambitions in Forests and Streams]).
