Zhao Ji (1082~1135), a native of Zhuoxian County, Hebei Province, was Emperor Huizong of the Northern Song Dynasty and a famous calligrapher and painter. He was politically incompetent and appointed treacherous ministers such as Cai Jing and Tong Guan, which caused the Song Dynasty to retreat steadily in the face of the invasion of Jin soldiers. He was also captured and sent to the north for many years. But in terms of art, he was the ancient emperor with the highest artistic achievements in China. His calligraphy is a mixture of various calligraphy styles, drawing on the strengths of others and making him unique, creating a "thin gold calligraphy" style that is thin, straight and crisp, with edges as sharp as orchids and bamboos. This is an original creation in the history of calligraphy and reflects a high degree of artistic accomplishment and skill. In terms of painting, regardless of landscapes, flowers, birds, or figures, he is able to "contain objects and give them shapes at will, and the brush drives nature and originates from the ends of the hair, so that all things can achieve their full physiology." He especially loved painting flowers and birds, and created his own "courtyard style", which was full of richness and nobility, bringing flower and bird painting into its heyday. He also advocated the compilation of "Xuanhe Painting Book" and "Xuanhe Calligraphy Book", which compiled a large number of famous calligraphy and paintings and became important materials in the history of Chinese calligraphy and painting. His handed down works include "Pictures of Wintersweet Mountain Birds", "Pictures of Five-Colored Parrots", "Pictures of Golden Pheasants in Lotus", "Thousand-Character Essay in Cursive Script", etc.
