Paper art. Originated in the Han Dynasty of China, the ancient paper carving art was mainly bred in the soil of folk art, and its development was slow but never stopped. Although the form remained unchanged, it did not lose its innovative spirit. Among them, the paper-carved lanterns with strong folk charm created a classic chapter of Chinese paper-carving art on the basis of drawing on the artistic modeling of palace lanterns. Paper sculptures are also called paper reliefs. Its origin can be traced back to the invention of paper in the Han Dynasty in China and the improvement of paper in Germany in the 16th century.
