Western paintings were Western oil paintings at that time. Oil paintings originated in Europe and were invented by the Dutch in the 15th century. They used linseed oil to blend the pigments and painted on treated cloth or boards. The oil paints do not change color after drying. The color harmony will not become dirty, and the painter can paint rich and realistic colors. Western painting rewrites reality, Chinese painting emphasizes artistic conception. In short, the two paintings are dominated by two concepts. When looking at Chinese paintings, the emphasis is on between the likeness and the non-likeness, to feel the humanistic spirit embodied in the paintings and the interest pursuit of traditional Chinese intellectuals. Western painting pursues such things as human anatomy and geometric composition. The pictures are similar to photography, which is uninteresting.
