Kong Keqi, a Yuan Dynasty man, wrote in Zhi, "Therefore, Song bamboo slips like to pick small fragrant gold bottles such as red and red, or some people paint them with gold as the bottom. The world still exists, and the most important thing is. Or silver or copper or tin. " Cao Zhao and Wang Zuo in the Ming Dynasty also pointed out in the New Gegu Yaolun that "the things in the inner government of the Song Dynasty were mostly made of gold and silver (inner tubes)." The carved red lacquerware in the Song Dynasty was heavy, because many tires were made of precious metals such as gold and silver. The exquisite carving method of red lacquerware in Song Dynasty has always been praised by scholars and collectors in Ming and Qing Dynasties. Wen Zhenheng, an Amin scholar, wrote in "A Long History": "The exquisite carver is more important than the Song Dynasty. People say that gold and silver tires are the most ridiculous. The beauty of the cover lies in its skillful knife technique, hidden front, fresh pen and ink, thick paint, picturesque landscapes, pavilions, figures, birds and animals, which is an excellent ear! In the Yuan Dynasty, Zhang Cheng and Yang Mao were also famous for their skills. Made in Guo Chao Orchard Factory, the knife method is better than Song Shang. " Huang Dacheng, an Amin, wrote in "Brick Decoration": "Picking red means carving red paint. The system of Song and Yuan Dynasties is clear, smooth and delicate. There are also inscriptions, which are as exquisite as those that see the black line on the side of the knife. " Gao Lian, an Amin writer, wrote in Yan Xianqing's Appreciation Notes: "Song people carved red lacquerware, such as boxes used in the palace, mostly with gold and silver as tires and thick piles of red lacquerware, up to dozens or hundreds of layers, and began to carve figures, towers and flowers. The skill of knife cutting is picturesque. " Zhang, an Amin, wrote in "The Secret Collection of Qing Dynasty": "In the Song Dynasty, red lacquerware was carved, and most of the people used in the palace were made of gold and silver. The beauty lies in the skillful use of knives, the hidden peaks are not exposed, the use of Zhu is fresh, the paint is extremely thick without cracks, and the figures carved in the pavilions and mountains are picturesque. " Xie Kun, a Qing Dynasty man, wrote in Zoyu: "In the Song Dynasty, there were carved lacquer plates and boxes, and the knives went into three layers, and the calligraphy and painting were extremely exquisite. In fact, some people regard gold as a fetus and cover up the contents. There are silver tires and gray tires among the people, all of which are exquisite. " A Qing wrote in "The Continuation of Bone Dong": "A small box of lacquerware from the Song Dynasty, which is less than one inch in diameter, has a golden bottom, carved dragons, scales and tendons, and claws with bone angles, seems to be generated. I have seen Qi Diao in my life. This is the first one, not comparable to the lacquerware of the Ming Dynasty. "
