Paper was first made 2000 years ago in China. It was made from pulped rags and old fishing nets, drained on a sieve made of bamboo! Paper may not immediately seem to be an ideal building material, but it is light and cheap, and allows a certain amount of light to pass through it. It is ideal for use with bamboo, which is also very light. Paper has been used in China and Japan for centuries to make screens and internal sliding walls in houses. Although these are not soundproof, they are very attractive and easily replaced if damaged.

Paper making is one of the inventions by Chinese. 105 A.D. is often cited as the year in which papermaking was invented. In that year, historical records show that the invention of paper was reported to the Eastern Han Emperor Ho-di by Ts'ai Lun, an official of the Imperial Court. Recent archaeological investigations, however, place the actual invention of papermaking some 200 years earlier. Ts'ai Lun broke the bark of a mulberry tree into fibres and pounded them into a sheet. Later it was discovered that the quality of paper could be much improved with the addition of rags hemp and old fish nets to the pulp. The paper was soon widely used in China and spread to the rest of world through the Silk Road. An official history written some centuries later explained: In ancient times writing was generally on bamboo or on pieces of silk, which were then called it. But silk being expensive and bamboo heavy, these twoich materials were not convenient. Then Tsai Lun thought of using tree bark hemp, rags, and fish nets. In 105 he made a report to the emperor on the process of paper making, and received high praise for his ability. From this time paper has been in use everywhere and is called the "paper of Marquis Tsai."

In few years, the Chinese began to use paper for writing. Around 600 A.D. woodblock printing was invented and by 740 A.D., The first printed newspaper was seen in China.

To the east, papermaking moved to Korea, where production of paper began as early as the 6th century AD. Pulp was prepared from the fibers of hemp, rattan, mulberry, bamboo, rice straw, and seaweed. According to tradition, a Korean monk named Don-cho brought papermaking to Japan by sharing his knowledge at the Imperial Palace in approximately AD 610, sixty years after Buddhism was introduced in Japan.

Along the Silk Road, we learned that paper was introduced to Xinjiang area very early according to the archaeological records. The paper found at Kaochang, Loulan, Kusha, Kotan, and Dunhuang sites dated as early as the 2nd century. The technique eventually reached Tibet around 650 A.D. and then to India after 645 A.D. By the time Hsuan Tsang from China arrived to India in 671 A.D., paper was already widely used there.
