中国是造纸、印刷术、火药、指南针四大发明者,有的人现在都不愿提起这事了,说是中国现在这么落后,老说祖先的光辉业绩,颇有自我安慰之嫌。这不无道理,但也不尽全面。认真研究老祖宗何以由先进而变为落后,我们该如何由落后变为先进,这可是真正的有志气者。 China is the inventor of the four major sources of papermaking, printing, gunpowder and compass. Some people are reluctant to mention this now. They say that it is too comforting for China to be so laggard and to always say the glorious achievements of its ancestors. This is not unreasonable, but not exhaustive. It is truly ambitious to carefully study why ancestors changed from being advanced to backward and how we should become backward from backwardness.
