Printing & Information

The oracle bones of the Shang gave way to cast bronze inscriptions, which gave way to bamboo and wooden slips (简牍) — the dominant medium from roughly the fifth century BCE through the early centuries CE. Slips were unwieldy in bulk: the Shiji reportedly required 130 cartloads to move. Silk offered a lighter surface but at prohibitive expense. The breakthrough arrived when the eunuch Cai Lun (蔡伦) standardized papermaking from bark, hemp, and rags around 105 CE — though earlier paper fragments have been recovered from Han-era sites. Paper spread westward along the Silk Road only in the eighth century, reaching Europe in the twelfth. In China, cheap and abundant paper triggered an expansion of literacy and documentation whose scale was not equalled elsewhere until Gutenberg.

Woodblock printing (雕版) emerged in Tang China and flourished in the Song, enabling the mass reproduction of Buddhist texts, almanacs, and the Confucian classics. The technology fitted the character set naturally: a skilled carver cut an entire page — characters, illustrations, commentary — as a unified relief surface. Bi Sheng (毕昇) invented fired-clay movable type around 1040 CE, and metal movable type appeared in Korea by the thirteenth century. Yet movable type remained a secondary technology in China for a paradoxical reason: the sheer scale of the character inventory (a functional printing shop required several thousand individual type pieces, with multiple copies of high-frequency characters) made composition slow, while carvers could produce a woodblock page with comparable speed. The economic calculus did not favor movable type for most Chinese print runs until the modern era, making the contrast with Gutenberg's transformative impact on the Latin alphabet a pointed illustration of how script structure shapes technology adoption.

The encounter between Chinese characters and industrial modernity was prolonged and at times brutal. The nineteenth-century Chinese typewriter required operators to hunt among thousands of slugs on a tray — a machine that demanded learning and physical memory as much as typing skill. In the early twentieth century, reformers like Qian Xuantong argued that the script itself was the obstacle to national modernization, prefiguring the romanization debates. The turn came through a series of technological leaps: Wang Xuan's (王选) laser typesetting system in the 1970s–80s (the Hua-guang system) allowed characters to be output at full print quality from digital descriptions, ending the era of manual type-setting and winning him the title “father of modern Chinese typesetting.” Input methods — phonetic pinyin (拼音) and stroke-based wubi (五笔) — resolved the keyboard problem. The Unicode/ISO 10646 CJK Unified Ideographs block, finalized through the 1990s, encoded tens of thousands of characters into a universal standard, at last giving Chinese (along with Japanese and Korean) a stable seat in the global information infrastructure.
