I hope you can help me correct the inappropriate part. Thank you! Shen Kuo was an outstanding scientist of the Northern Song Dynasty(960-1127) of China. Meng Xi Bi Tan(The Dream Pool Essays), the collected works of literay sketches written in his later years, represented a milestone in Chinese scientific history. Printed books began to circulate after the first edition. Bi Sheng's invention of movable type printing was only recorded in this book, which was proved to be precise. Despite the fact that scholars of all ages had written many book, none of thme was on a par with it. Excerpts are as following:"......" After he died, Bi Sheng's movable type characters were got and kept by Shen Kuo's sons and nephews, which proved that Shen Kuo hand an understanding about Bi Sheng's invention, so the records seemed to be credible. This paragraph about Bi Sheng's invention has been translated in French, English, German and Russian, and was recognized by the whole world. Such abundant resources as paste,pine resin and wax, materials used for movable type printing recorded by Shen Kuo, were found in Yingshan. It was obvious that yingshan was related to Bisheng's invention, for it had fundamental conditions in terms of history, geography, economy and resources. Apart from Bi Sheng's tomb, the tomb of Bi Sheng's descendant Bi Wenzhong, and other discoveries were also found. It was by no means accidental, and proved that Bi Sheng, inventor of movable type printing was from Yingshan. His date of death and burial was affirmed from his inscription. He died in the third year of the reign of Emperor Huangyou(1051 A.D.), and was buried in February in the fourth year of the reign of Emperor Huangyou(1052 A.D.)
