In 2012, Yuanhua Jia created his own style, which is also unique artistic style in the world. The delicate lines displayed in these paintings were carved with a knife before the oil paint surface dried. Unlike conventional painting, this method of creation is extremely challenging. Since the paint typically dries within 24 to 72 hours, carving time is limited. The elasticity of the canvas and the slippery wetness of the paint make each straight line a challenge. It requires intense concentration and a steady hand to control the knife's direction. A single mistake can ruin all the work.

The oil painting knife-line engraving works combine the exquisite beauty of Song Dynasty fine brushwork, the color expression of printmaking and the art of sculpture. They are unique and distinctive in the field of art. His acrylic paintings are equally stunning and refreshing with their humorous approach and unique perspective.

In his works, fallen flowers evoke sadness, suggesting the rapid disappearance of historical buildings, the forgetting of traditional culture, and the lack of successors for traditional handicrafts. The pandas in his works represent more than just people. They carry a deeper meaning. Beautiful natural environments and exquisite historical buildings, like endangered pandas, need to be carefully protected.
