In 105 AD, Cai Lun presented an improved papermaking process to the Chinese emperor, revolutionizing the way information was recorded and shared. By using mulberry bark, rags, and fishing nets, Cai Lun created a more efficient and durable form of paper that would become the standard for centuries. This innovation significantly contributed to the spread of literature, education, and bureaucracy in China and eventually throughout the world. The invention of paper is often regarded as one of the key advancements in human communication and culture.

The invention of paper by Cai Lun around 105 AD revolutionized writing materials, enabling widespread literacy and preservation of poetry across East Asia. This innovation allowed poets like Li Bai and Du Fu to flourish, as their works could be easily copied and disseminated, thus enriching Chinese literary traditions.
