The Kaiyuan Za Bao, often called the world’s first magazine, began circulating through Tang dynasty China in 713 CE. Scribes hand-transcribed court news onto silk, then dispatched it from the capital Chang’an to officials across the provinces for over two decades. It’s a reminder that regular, structured news-sharing took root far earlier than Western timelines suggest.
The Dunhuang star map, completed around 700 C.E. during China’s Tang dynasty, charts more than 1,300 stars across 13 panels — the oldest known complete star atlas in the world. Sealed in a cave near Dunhuang for nearly a millennium, it reveals just how sophisticated early Chinese astronomy had already become.
Wu Zetian declared herself emperor of China in 690 C.E., founding the Zhou Dynasty at age 65 after decades navigating the Tang court as concubine, empress, and regent. During her 14-year reign, she expanded the imperial examination system, opening government service to talent beyond the aristocracy. She remains the only woman to hold the title in over 2,000 years of Imperial Chinese history.
The Giant Wild Goose Pagoda rose in Chang’an in 652 C.E., built by the monk Xuanzang to shelter the 657 Sanskrit texts he had carried home from India. He supervised construction himself, using rammed earth and brick. Fourteen centuries later, the tower still stands in modern Xi’an, its Tang-dynasty core wrapped in Ming brick.
Paper money began quietly in 7th-century Tang Dynasty China, when merchants tired of hauling heavy bronze coins started depositing them at regional offices in exchange for lightweight paper certificates called fei-ch’ien, or “flying money.” Redeemable at the capital, these slips weren’t quite currency yet, but they planted the idea that trust itself could travel.
In 646 C.E., a young monk named Bianji sat down in Tang China to organize his teacher Xuanzang’s astonishing 19-year journey across the Silk Road into a single text. The result, spanning 12 volumes and 110 regions, still guides archaeologists today — from Bamiyan’s Buddhas to the ruins of Nalanda.
China’s Grand Canal took shape around 605 C.E., when Emperor Yang of the Sui Dynasty ordered millions of laborers to stitch together older waterways into a single 2,500-kilometer spine linking the Yellow and Yangtze rivers. It let grain flow from the fertile south to the dry north, quietly reshaping how a vast civilization fed and held itself together.
The Qieyun, compiled by Lu Fayan in 601 C.E., began as a dinner-party argument in Chang’an about how Chinese characters should be pronounced. Eight scholars from north and south disagreed; Lu spent the next twenty years synthesizing their debate into 12,158 characters across 193 rhyme groups. It remains our clearest window into Middle Chinese.
The Sui Dynasty reunified China in 589 C.E., ending nearly three centuries of fragmentation under founder Yang Jian. In less than four decades and just two emperors, the Sui built the Grand Canal, replaced hereditary appointments with merit-based exams, and laid the administrative foundation the celebrated Tang Dynasty would inherit.
Chinese sulfur matches first appear in the historical record in 577 C.E., when court women during the fall of the Northern Qi reportedly used pine slivers soaked in sulfur to catch a spark. By 1290, they were ordinary market goods in Hangzhou — perhaps the earliest commercial tool for making fire portable.
