澄清堂帖为宋刻汇帖，帖石早佚，拓本流传极少，继善堂珍藏。
米芾为我国宋代杰出的书画家、收藏家，尤以书法见长，米芾七岁就开始学书，由唐溯晋，遍学诸家。
他在《自叙帖》中讲述自己学书生涯，学柳《金刚经》，后乃学欧阳修，如印板排算，又仰慕褚遂良，学他时间最长。又学段季(展)转折肥美，八面皆全。不仅博取众家之长而且学书极为勤勉，他曾自言：“一日不书，便觉思涩，想古人未尝片时废书也。”他在《元日帖》中又言：“元日明窗焚香，西北向吾友，其永怀可知。展《文皇大令》阅，不及他书。临写数本不成，信真者在前，气焰慑人也。”
据宋岳珂《宝真斋法书赞·米元章临右军四帖》引米友仁跋云:“先臣芾所藏晋唐真迹，无日不展于几上，手不释笔临之，夜必收于小筐，置枕边乃眠。”元旦日犹不辍临帖而且将先贤真迹珍护甚之。可见米芾对学习书法的浓厚兴趣和痴迷状态。
米芾虽然生活在追求革新的北宋时期，但却与苏轼“出新意于法度之中，寄妙理于豪放之外”和黄庭坚的“随人作计终后人”自成一家的思想完全相反，他反而崇古，在评价前代书法时，认为有古法者为美，反之则丑。在米芾的书论中，卑唐崇晋的观点十分明显。米芾卑唐崇晋的行为阐释了米芾“尚意”的艺术思想。
--------Introduction in English--------
Clarification Tang Tie is a collection of Song Dynasty carvings. Tie stone is lost early, rubbings are seldom circulated, and Jishan Tang collects them.
Mi Fu was an outstanding painter and collector in Song Dynasty, especially in calligraphy. Mi Fu began to learn books when he was seven years old. From Tang Dynasty to Jin Dynasty, he studied all over the world.
In his Self-Narrative Tie, he narrated his career in learning books. He learned Liu's Diamond Sutra, and then Ouyang Xiu, such as printing board calculation, and admired Zhu Suiliang, who had studied him for the longest time. The turning point of Duan Ji (Exhibition) is fat and beautiful. Not only did he gain the merits of many families, but he was also very diligent in learning books. He once said to himself, "If you don't read a book in a day, you will feel astringent and think that the ancients did not waste it for a while." In his "Yuanye Tie", he also said: "Yuanye bright window incense burning, northwest to my friend, its eternal bosom knows. Reading Wenhuang Daling is not as good as other books. Before writing a few books, the faithful are in front of them, and their flames deter them."
According to Song Yueke's Four Ties of Baozhenzhai Calligraphy Zan Mi Yuanzhang Linyoujun, Mi Youren quoted Bayun as saying: "The authentic works of Jin and Tang Dynasty hidden by the first minister Fu are displayed on several occasions every day, and they will be kept in small baskets at night, while sleeping on pillows." On New Year's Day, we keep posting and cherish the true works of our ancestors. It can be seen that Mifu has a strong interest in learning calligraphy and is obsessed with it.
Although Mi Fu lived in the Northern Song Dynasty in pursuit of innovation, he was totally contrary to Su Shi's thought of "innovating in the law, sending wisdom out of boldness" and Huang Tingjian's thought of "making plans for future generations by others". On the contrary, he worshipped the ancients. When evaluating the former generation's calligraphy, he thought that those who had the ancients calligraphy were beautiful, and vice versa were ugly. In Mi Fu's book theory, the viewpoint of "Beitang and Chongjin" is very obvious. Mi Fu's behavior of worshipping Jin in Tang Dynasty explains Mi Fu's artistic thought of "advocating meaning".
