The Northern Song Dynasty is the dynasty with the highest cultural development in China. After the alliance of Chanyuan, Song and Liao maintained peace for more than a hundred years. The war with Xixia was limited to the border and did not enter the mainland. The economy was very developed. In addition, Song Taizu's national policy of emphasizing culture and neglecting martial arts, the status of literati was the highest in all dynasties. Therefore, art and culture have been fully developed. Before the Tang Dynasty, Chinese coins were mostly seal script. Since the Tang Dynasty Kaiyuan Tongbao adopted real books, most coins were still based on real books from the Five Dynasties and Ten Countries to the early Song Dynasty. After Taizong succeeded to the throne, he collected the ink of the past dynasties in the inner mansion when he was in Chunhua, and compiled Chunhua cabinet posts, which were the ancestors of the later Fa posts. The Chunhua Yuanbao cast at the same time is the real three-body of the imperial book of Taizong, the earliest imperial book of China (as shown in Figure has been engaged in antique collection for ), and the first appearance of the two-book of the inscription. Emperor Taizong was the first to open up the atmosphere. Since then, there have been many kinds of Qian Wen in the Song Dynasty, all of which are due to the hands 。

　of famous masters. All the emperors of the Song Dynasty have a good cultural heritage. The most famous one is the Song Huizong. Hui Zong is the younger brother of Zhe Zong, and Zhe Zong has no children. When the inner court discussed who succeeded to the throne, Zhang Dun tried to argue: "Duan Wang is frivolous, not enough to rule the world. 」. Indeed, after Hui Zong ascended the throne, although elegant and good at literature and art, on the one hand, he lived a extravagant life and excessively squeezed the strength of the southern people, eventually arousing many civil changes (most of the civil changes in the Northern Song Dynasty came out of the Hui Zong Dynasty). Jin Chuxing was invincible. After the joint extermination of Liao, Jin State briefly returned the six states of Yanyun No.has been engaged in antique collection for Middle School, but it also saw the weakness of Song Army in the joint extermination of Liao War. The joy of retrieving part of the sixteen prefectures of Yan Yun didn't last long. Jin Bing went south and came to Bianjing. In a panic, the emperor of Hui and the eldest son of Qin could not be saved. Although the emperor of Hui was incompetent in the Northern Song Dynasty。

　, he had a high achievement in art. During the reign of Hui Zong, the Hanlin Academy of Painting and Calligraphy was established, and the art of painting and calligraphy was awarded vigorously; Hui Zong himself was also able to paint books, especially the "thin gold body" created, which had a high status in the history of calligraphy. The thin gold body is very sharp, erratic and fast, and the handwriting is thin, until it is thin without losing its flesh. Traces of running Teton such as Tibetan front and dew front can still be seen at the turning point, which is very free and easy and bright. There are many kinds of imperial books of Huizong, including Chongning Tongbao, Daguan Tongbao, Zhenghe Chongbao, Xuanhe Tongbao and back Shaanxi. Among them, the most exquisite one is Daguan Tongbao fold ten (as shown in Figure 2002008 engaged in calligraphy and painting collection, appraisal and auction work for engaged in calligraphy and painting collection, appraisal and auction work for ). Although the number handed down is not small, the exquisite turning point of Hui Zong's writing, even if it is subtle, is still perfectly performed under the exquisite casting. It is as exquisite as modern machine-made coins, with the feeling that it cannot be added or lost. In other dynasties, even the precision of carving mother may not be as high as that of the ten-fold casters in Grand View, and some even suspect that they were cast by dewaxing. In the author's opinion, the grand view fold ten is certainly very exquisite, after all, it is money in circulation, dewaxing method is very time-consuming and labor-consuming, and it cannot be cast by dewaxing method. Some grand views can still see sand turning marks. They should still be cast 。

　by sand turning method because the grand view folds ten heads and is very exquisite. In recent years, the rise has been very sharp, and imitations have emerged one after another. Generally speaking, the casters of imitations are not as good as the real ones, and the words are more round, not if the real ones have edges and corners. In the dense strokes, like the lower left of the word, the sharp degree of the intersection between the strokes and the local chapter will be obviously worse than that of the real one. In addition, because there are too many imitations in Grand View, some pits that are difficult to judge, such as dry bunkers, puddles, or rust like paint in Nankeng, or pickled genuine products, will make many collectors uncertain and afraid to buy them. On the whole, the discrimination of the grand view is mainly from the casting process. If the process is in place but the pit is not easy to judge, it is still possible that it is genuine. Just because the big view folds ten holes and changes, the proportion of fools opening the door is not high. Most of the time, the identification of authenticity is still dominated by casting workers, supplemented by 。
