one thing everyone should know about China is that its Long history allows many great inventions to emerge. Many Chinese inventions sprung from daily necessity and are always ahead of its world counterparts in creativity. For example, paper making. Paper was invented in 105A.D during the reign of han dynasty, although as latest revelations tell us paper might have existed even 200 years earlier, used by the ancient Chinese military force. This vital invention was spread out of China via Silk Road, giving writing a better tool.
用发明来写吧。本身历史知识渣，楼主应该可继续写下去，比如茶的发明，silk（绸缎？丝绸） 的发明
