Exquisite Song rubbings are priceless. For example, Huang Tingjian of the Song Dynasty said: "The tomb of Confucius Temple is carved in Zhenguan, and two thousand gold can be bought." Sun Chengze's "Gengzi Ji Xiaoxia" says: "Song Tuo's" Daguan Post "has two kinds of yellow and white papers, and opinions vary ... This post says that Putian Fangkai once spent millions on it in the Song Dynasty." It is precisely because of Seiko's Song Tuoben that its price is so expensive. In order to make huge profits, some booksellers, Tiejia, used various methods to do some operations, faked and pretended to be Song Tuo, developed some new rubbings with good paper and ink, and steamed (smoked) old works, which seemed to be a thousand years ago or eight or nine hundred years ago. The specific method is to brush the paper into yellow brown, then steam it, put it in a damp place, make it moldy and frosty, and then ventilate it to absorb moisture. Through the above operations, it is processed into the appearance of "Song Tuo". After loading, add a coat and decorate it with Song or Ming brocade, which can serve as "Song Tuo". However, although the bookseller's counterfeiting technology is superb, he can't escape the discerning eye of the appraiser.
Generally speaking, according to incomplete statistics, there are few existing Song rubbings in China, but the total number far exceeds that of Tang rubbings. Generally speaking, these Song rubbings handed down from generation to generation have many inscriptions, few inscriptions, and many inscriptions in Han and Tang Dynasties, especially in Tang Dynasty. For example, there are many inscriptions in the Tang Dynasty, such as those written by Huang Tingjian for the monarch's poems, those written by Yu Gonggong, those written by Jiucheng Palace for Liquan, the preface of Wang Shengjiao in Huairen, many pagodas and the tablets of Taoist masters. There are Shi Guwen, Taishan Stone Carvings, Confucius Monuments, Huashan Temple Monuments, Shi Chenbei Monuments, Liu Xiong Monuments, Cao Weifan Monuments, Wu's Stone Carvings of Tian Xi Ji Gong, and Song Tuo's Daguan Post.
