The first point: it is not easy to copy the words of ancient emperors, and no one dared to copy them in Song Dynasty. If someone tries to imitate them, they may be suspected of imitating imperial pens. Furthermore, if someone imitates the emperor's handwriting, it will inevitably lead to social unrest. Therefore, Song Huizong's imperial brush was not widely circulated among the people, and later learners also lost more precious materials.
The second point: Song Huizong, as a loser, later emperors and scholars will think that the handwriting of a conquered king is not worth pursuing. In the Ming Dynasty, the emperor praised Song Huizong's calligraphy, and courtiers immediately thought that Song Huizong was the king of national subjugation. In Qing Dynasty, Qianlong once praised Song Huizong's thin golden body, and the same Qianlong once again mentioned the topic of the king of national subjugation. From this point of view, there are a lot of factors why the thin gold body has not been popularized in Song Huizong.
The third point: First of all, the font "Shoujinti" did not form a complete teaching system in later generations because it was copied less. Secondly, the manual body has high requirements for pens and paper for writing, and most people rarely choose to study it. Moreover, it is difficult to keep the golden body, and it is difficult for many people to keep the golden body.
Under the influence of these factors, thin gold has not been popularized.
