Guo Jin was born in 1964 in Chengdu, in Sichuan Province, and attended the Sichuan Fine Arts Institute, graduating from the oil painting department in 1990. His paintings frequently take children as his subject matter in a juxtaposition of youth with China's own development, and idealism lost. After graduating in the early '90s, he showed modestly within China, significantly in Guangzhou Biennale's 1992 oil painting exhibition, in which many of his Sichuan peers also showed works. Since then, as art institutions and infrastructure have grown within China, he has participated in an increasing number of shows, often with his brother, the artist Guo Wei. His bold use of colour and skill at creating silk-screen-like texture in oil have garnered him the attention of many gallerists and collectors. He lives and works in Chongqing and Beijing.
