Meng Qian's Bi Tan describes politics, military affairs, law, personnel, some anecdotes, art and stories at that time. The intrusion of taxes on the people, the advantages and disadvantages of northwest and north, etiquette and the evolution of ancient music are well recorded. This book has important reference value for studying the society, politics, science and technology and economy of the Northern Song Dynasty. Meng Qian Bi Tan also reflects Shen Kuo's thoughts and research methods, and is the main reference material for studying Shen Kuo's scientific thoughts. According to textual research, Meng Qian Bi Tan received academic attention after its publication, and was soon published and engraved. The original 30-volume edition of Meng Qian Bi Tan has more contents than the current edition, but it has long been lost, and only 26 volumes have been engraved and handed down in the Song, Yuan, Ming and Qing Dynasties. There was an engraving of Yangzhou in the Song Dynasty, and the main road was reprinted two years ago. Unfortunately, the engraving of the Song Dynasty does not exist today, so the oldest edition at present is the engraving of Chen Renzi Dongshan Academy in Dade Nine Years of Yuan Dynasty (1305) collected by the National Library. Among the three popular editions, namely, the original edition, the supplementary edition and the sequel edition, Renhai was first published. The block-printed edition of Dongshan Academy in Dade's Nine-Year Plan is very large in format, but very small in binding. The binding is a unique butterfly suit that was popular at that time. 1956, Shanghai Publishing Company published Hu Daojing's "Meng Qian Bi Tan School Certificate", with detailed textual research. Zhonghua Book Company published a new edition of Hu Daojing's Meng Qian Bi Tan in 1957, which is very readable. Meng Qian Bitan is also very influential abroad. As early as19th century, it was famous for its records of movable type printing. Since the beginning of this century, people in France, Germany, Britain, the United States, Italy and other countries have made a systematic and in-depth study of Meng Qian Bitan and introduced it to the public. As early as the middle of19th century, Shen Kuo's representative works were printed in movable type, making it the first country in the world to print Meng Qian's Bi Tan in movable type. Since 1978, Japan has published a Japanese translation of Meng Qian Bi Tan in three volumes. Gu summarized three advantages of engraving books in Yuan Dynasty in Records of the Day: 1, the mountain chief in charge of the academy was proficient in proofreading, which made the book proofread carefully and had high edition value; 2. Strong funds, engraving and typesetting, and high quality printed books; 3, the book version is hidden in the academy, which is extremely convenient for printing and circulation. These advantages are prominently reflected in Meng Qian Bi Tan carved by Dongshan Academy, which also makes readers have a further understanding of the large format and small format of Meng Qian Bi Tan carved by Dongshan Academy. The Yuan version of Bitan Dongshan Academy has a Zhu seal in front of the volume, and there are also seals on the book collection of Pingyang King, seals on the book, and seals on the two refuge books of Jiazi Bingdejun Qian Runwen and his wife. The book was hidden in the palace in the Yuan Dynasty, and was later acquired by Zhu Yuanzhang, the Ming emperor, and handed over to Prince Zhu Biao, and then returned to the "Wenyuan Pavilion" in the palace. Clear out of the palace, has been collected by Art Cloud Jingshe and Songjiang Han. At that time, private books were kept secret, and only a few people had seen this book. This book was later collected by the famous bibliophile Chen Chengzhong. After Chen Chengzhong moved to Hong Kong, in 1965, he planned to sell a number of rare books, including Meng Qian's Bi Tan. In order to avoid the outflow of precious cultural relics, Premier Zhou Enlai personally asked and instructed the Ministry of Culture to assign special personnel to handle it. When the national economy was not well off, he spent a lot of money to buy it back, which became a story in the book. 1976 was photocopied and published by Cultural Relics Publishing House. In 2003, the "China Rare Books Recycling Project" was also produced and published, which provided convenience for the public.
