国画, or Chinese traditional painting, is a unique art form that has evolved over thousands of years. It typically uses ink and watercolor on rice paper or silk, emphasizing brushwork and the use of natural materials. The subjects often include landscapes, flowers, birds, and animals, reflecting the beauty of nature and Chinese philosophy. This art form is characterized by its emphasis on expression and technique rather than realistic representation. Artists like 齐白石 and 张大千 are renowned for their contributions to 国画, showcasing the rich cultural heritage of China. The practice often incorporates calligraphy and poetry, adding layers of meaning to the artwork.
