Although the Sui dynasty was relatively short (581-618), much was accomplished during its tenure. The Grand Canal was one of the main accomplishments. It was extended north from the Hangzhou region across the Yangzi to Yangzhou and then northwest to the region of Luoyang. Again, like the Great Wall works, the massive conscription of labor and allocation of resources for the Grand Canal project resulted in challenges for Sui dynastic continuity. The eventual fall of the Sui dynasty was also due to the many losses caused by the failed military campaigns against Goguryeo. It was after these defeats and losses that the country was left in ruins and rebels soon took control of the government. Emperor Yang was assassinated in 618. He had gone South after the capital being threatened by various rebel groups and was killed by his advisors (Yuwen Clan). Meanwhile, in the North, the aristocrat Li Yuan (李淵) held an uprising after which he ended up ascending the throne to become Emperor Gaozu of Tang . This was the start of the Tang dynasty , one of the most-noted dynasties in Chinese history.
Censorship: Qin practiced total censorship. He persecuted scholars and destroyed books. He defined useless books as any book about anything except books about medicine, agriculture, or prophecy. Useless books were burned. Over 400 scholars who refused to turn in books were either buried alive or sent to work on the wall. Qin did not believe in any education for the common man. According to Qin, the more time people spent studying, the less time they had to grow food. He especially disliked the teachings of Confucius. He had all Confucius’ books burned.
