As an extremely important painting system in Chinas traditional art, flower-and-bird painting has become a core artistic medium for constructing and showcasing the ideal realm of harmonious coexistence between humans and nature through brush and ink, with its unique aesthetic perspective and profound cultural accumulation. Entering the 21st century, the existing themes of traditional flower-and-bird painting can no longer fully respond to the contemporary aesthetic trends of continuous evolution and diverse coexistence. Through deep exploration of regional expressions and other paths for diversified integration, it has become an inevitable trend to meet the demands of today’s visual culture. Mr. Li Wei, a master of flower-and-bird painting with profound traditional scholarship and a broad contemporary vision, exemplifies the creative transformation and innovative development of traditional freehand flower-and-bird painting in the present era, thanks to his authentic freehand techniques, rich regional characteristics, and innate aesthetic sensibility.
