Jin Nong

Jin Nong also made money as a writer and general entrepreneur. He was known to travel with a number of disciple-servants who assisted in the production of ink stones and lanterns to which he would add a personal artistic touch. It was through the sale of these items that Jin achieved financial independence; his single, failed attempt to compete for office was in the year 1736. He became widely known for his writings, but when his health began to fail, painting became his principal source of income and he in fact acknowledged the use of ghost-painters as a way to increase production. One such understudy, Luo Ping (whose name is sometimes rendered "Lo Ping"), also edited some compilations of his works. He continued to write throughout this time and was a critic as well as a dealer of paintings. There is some confusion about Jin's year of death, but it was most likely 1763 or 1764.
He also had a reputation as a calligrapher creating a style he called "lacquer calligraphy." Provided by Wikipedia
