Sufan Oh is the son of the famous calligrapher Cheongnam Oh Jebong from Jinju, Gyeongnam. In general, calligraphy is known for its “ilpilhwiji” style, which involves making one stroke at a time. With just a few strokes on a monochromatic background, Oh's works are reminiscent of oriental calligraphy, even though he uses oil paints. The artist's vigorous brushstrokes sometimes become waterfalls and sometimes fountains. By combining the characteristics of Western abstract painting with the traditional handwriting and ink methods of Eastern calligraphy, his works convey a futuristic and progressive feeling. In his studio, a sketchbook filled with countless pencil and pen sketches is a testament to the artist's belief that “there is no depth without repetition.”

Regarded as one of the founding fathers of Korean contemporary abstract painting, Oh combines Eastern calligraphy with Western surrealism, en plein air, and abstract art to express his unique sensibility and philosophy. With the support of the MAG Foundation, a famous French collector family that owns works by 20th-century European art masters such as Chagall, Matisse, and Kandinsky, Oh has garnered great attention among global collectors and has held successful solo exhibitions at the MAG Gallery in Paris. His works are in the collections of many of the world's leading art institutions, including the National Museum of Modern and Contemporary Art, Hoam Art Museum, Kumho Art Museum, Hansol Foundation, Seoul Museum of Art, Bibliothèque Nationale de Paris, Akiraikeda Foundation, and Fukuoka Art Museum.
