When Wang Chong wrote "Lunheng", although rough hemp paper was already available, this kind of paper was made of raw materials such as hemp and ramie. The texture of the paper was relatively rough and the fiber tissue was unevenly distributed, making it not suitable for writing. His book was written on bamboo slips and wooden slips. Shortly after Wang Chong's death, Cai Lun improved the papermaking technology and created paper suitable for writing.
Reader comments
I especially like Zhang Heng. He can still persist in studying under such difficult conditions. I really admire him. Moreover, he also invented the seismometer and made great contributions to astronomy. However, I kind of hate those who hinder the development of science. If they could work as hard as Zhang Heng, they might be able to make greater contributions! In short, this book gave me a deeper understanding of Chinese history and science, and it is well worth reading.
