According to legend, there is a story that an advanced examination of painting was held in the Song Dynasty, which brought together painters from all over the world. Mr. Evonne, the master of the emperor, wrote a question: "A little red in evergreen does not need much touching spring scenery." As a result, someone came first with a stroke of the pen. He painted a small building in the jungle. There was a beautiful woman upstairs by the window with a little lipstick on her lips.
