水墨画, or "ink wash painting," is a traditional Chinese art form that uses black ink and water to create expressive images. This technique emphasizes the use of brush strokes and the interplay of light and shadow, allowing artists to convey emotions and capture the essence of their subjects, often nature or landscapes. The style is characterized by its simplicity and elegance, often featuring elements like mountains, rivers, and flowers. Famous artists, such as 王羲之 and 张大千, have contributed to the development of this art form, making it an important part of Chinese culture and heritage.
