 for Jingde, Anhui province, where he invented the use of wooden movable type printing. The invention of wooden movable type was described in Wang Zhen's publication of 1313 AD, known as the Nong Shu (農書), or Book of Agriculture. Although the title describes the main focus of the work, it incorporated much more information on a wide variety of subjects that was not limited to the scope of agriculture. Wang Zhen's Nong Shu of 1313 was a very important medieval treatise outlining the application and use of the various Chinese sciences, technologies, and agricultural practices. From water powered bellows to movable type printing, it is considered a descriptive masterpiece on contemporary medieval Chinese technology.

 thoroughly damaged the economic and agricultural base of China during the conquest of it. Hence, a book such as the Nong Shu could help rural farmers maximize efficiency of producing yields and they could learn how to use various agricultural tools to aid their daily lives. However, it was not intended to be read by rural farmers (who were largely illiterate), but local officials who desired to research the best agricultural methods currently available that the peasants otherwise would know little of.

The Nong Shu was an incredibly long book even for its own time, which had over 110,000 written Chinese characters. However, this was only slightly larger than the early medieval Chinese agricultural treatise of the Chi Min Yao Shu written by Jia Sixia in 535 AD, which had slightly over 100,000 written Chinese characters.

 printing type with earthenware frame in order to make whole blocks. Wang Zhen is best known for improving its use by inventing wooden movable type in the years 1297 or 1298, while he was a magistrate of Jingde in Anhui province from 1290 to 1301. His main contribution was improving the speed of typesetting with simple mechanical devices, along with the complex, systematic arrangement of wooden movable types. Wang Zhen summarized the process of making wooden movable type as described in the passage below:
Wooden movable type had been experimented with by Bi Sheng
Bi Sheng

 in the 11th century, but it was discarded because wood was judged to be an unsuitable material that Bi Sheng found difficult to use. Wang Zhen improved the earlier experimented process by adding the methods of specific type cutting and finishing, making the type case and revolving table that made the process more efficient. In Wang Zhen's system, all the Chinese writing characters were organized by five different tones and according to rhyming, using a standard official book of Chinese rhymes. Two revolving tables were actually used in the process; one table that had official types from the book of rhymes, and the other which contained the most frequently used Chinese writing characters for quick selection. To make the entire process more efficient, each Chinese character was assigned a different number, so that when a number was called, that writing character would be selected. Rare and unusual characters that were not prescribed a number were simply crafted on the spot by wood-cutters when needed.

While printing new books, Wang Zhen described that the rectangular dimensions of each book needed to be determined in order to make the corrected size of the four-sided wooden block used in printing. Providing the necessary ink job was done by brush that was moved vertically in columns, while the impression on paper the columns had to be rubbed with brush from top to bottom.

 (1644 – 1911), wooden movable type was used on a much wider scale than even the previous Ming period. It was officially sponsored by the imperial court at Beijing, yet was widespread amongst private printing companies. The creation of movable type writing fonts became a wise enterprise of investment, since they were commonly pawned, sold, or presented as gifts during the Qing period. In the sphere of the imperial court, the official Jin Jian (d. 1794) was placed in charge of printing at the Wuying Palace, where the Yongzheng Emperor

 had 253,000 wooden movable type characters crafted in the year of 1733. Jin Jian, the official in charge of this project, provided elaborate detail on the printing process in his Wu Ying Tian Ju Zhen Ban Cheng Shi (Imperial Printing Office Manual for Movable Type). In nineteen different sections, he provided detailed description for:
  • type body
  • cutting the type
  • making type cases
  • form trays
  • strips in variable thickness
  • blanks
  • center columns
  • sorting trays
  • page and column rule forms
  • setting the text
  • proofing
  • printing
  • distribution of the type
  • and a schedule for rotation


There are notable differences between Wang Zhen's movable type process and Jin Jian's. Wang carved the written characters on wooden blocks and then sawed them apart, while Jin initiated the process by preparing type bodies before the characters were individually cut into types. For setting type, Wang employed a method of revolving tables where the type came to the workers, whereas Jin developed a system where the workers went to the organized type. Wang's frame was also added after the type had already been set, whereas Jin printed the ruled sheets and text separately on the same paper.

Agriculture

The main focus of the Nong Shu written by Wang Zhen was the realm of Chinese agriculture. His book listed and described an enormous catalogue of agricultural tools and implements used in the past and in his own day. Furthermore, Wang Zhen incorporated a systematic usage of illustrated pictures in his book to accompany every piece of farming equipment described. Wang Zhen also created an agricultural calendrical

For example, one of the many devices described and illustrated in drawing is a large mechanical milling plant

en, with an enormous rotating geared wheel engaging the toothed gears of eight different mills surrounding it. Of great interest to sinologist historians, Wang Zhen also outlined the difference between the agricultural technology of Northern China and that of Southern China. The main characteristic of agricultural technology of the north was technical applications fit for predominantly dryland cultivation, while intensified irrigation cultivation was more suitable for southern China. Furthermore, Wang used his treatise as a means to spread knowledge in support of certain agricultural practices or technologies found exclusively in either South or North that could benefit the other, if only they were more widely known, such as the southern hand-harrow
