He also recorded many achievements of our working people in science and technology in such works as “Meng Xi Bi Tan Tan” and “Forgotten Huai Hu Lu”. For example, Bi Sheng invented the movable type printing, a major achievement universally acknowledged in the world, leaving only the written records of his descendants from his hand. This is a precious document in the history of science and technology in the world. What we are proposing here is that as early as the 11th century, our country was able to extract relatively pure sex hormone preparations from large amounts of human urine. This brilliant accomplishment has also left the earliest and most complete and reliable No doubt, this is Shen Kuo another important contribution to the history of science and technology in the world.
