Meng Qian Bi Tan recorded in detail the outstanding contributions of working people in science and technology and their own research results, and reflected the brilliant achievements of natural science in ancient China, especially in the Northern Song Dynasty. Meng Qianbi's talk includes bi talk, bi talk and continuous bi talk. The twenty-six volumes of Bi Tan are divided into seventeen chapters, which are "story, dialectics, music, image, personnel, government, wit, art, calligraphy and painting, skill, utility, magic, strangeness, fallacy, ridicule, magazine and medical discussion" in turn.

In terms of nature, Meng Qian Bitan belongs to the category of notes. In terms of content, more than one-third of the space is used to describe and expound natural science knowledge, which is rare in notebook writing. Because Shen Kuo himself has a high scientific literacy, the scientific and technological knowledge he recorded is of great value, which basically reflects the scientific development level of the Northern Song Dynasty and his own research experience, so he is praised by modern people as "the coordinate in the history of science in China".

For example, Meng Qian Bi Tan-Volume 18-Skills correctly and in detail records the clay movable type printing invented by Bi Sheng Buyi, which is the earliest reliable historical data about movable type printing in the world and has been highly valued by the international literary and historical circles. In addition, other major scientific and technological inventions and figures in the Northern Song Dynasty were handed down from generation to generation by the records in this book. For example, the record of Yu Hao's "Wood Classic" and its architectural achievements, the ingenious method of three customs clearance in water conservancy projects, the mastery of calendar by Buyi Weipu in Huainan, the explanation of rainbow and Lu Longjuan by Sun Sigong from Dengzhou, the technology of "Tuangang" and "pouring steel" in Hebei, the application of "boil" by Qiang people in cold working and smelting, and the production of "dipping copper" are all treasures in the history of science and technology. The above description of Meng Qian Bitan's scientific and technological achievements in the Northern Song Dynasty is enough to make him famous in history. Moreover, the book also recorded many original opinions of Shen Kuo himself, which further promoted the scientific development of the Northern Song Dynasty.

Shen Kuo, a scientist in the Northern Song Dynasty, wrote a book on Meng Xi, which summarized many scientific and technological achievements in ancient China, mainly in the Northern Song Dynasty, and played an important role in the history of our country and the world. Needham, a British scholar, called Shen Kuo "the most outstanding figure in the history of science in China" and "Talk about Meng Xi" a "milestone in the history of science in China".
