Fu Sheng
Fu Sheng was a native of Jinan prefecture (濟南, in present-day Zouping or Zhangqiu, Shandong province), and was said to be a descendant of the legendary ancient ruler Fu Xi. He was a "boshi" (博士, "erudite") of the Qin dynasty. In 213 BC the First Emperor of Qin ordered the Burning of Books and killed many Confucian scholars. Risking his life, Fu Sheng hid a copy of the book in the walls of his house. He later escaped his hometown in the warfare that soon broke out and eventually ended the Qin dynasty. After the Han dynasty was established in 206 BC, Fu Sheng returned home and retrieved the scrolls. However, he was only able to recover 29 chapters; the rest (tens of chapters) had been lost to damage or decay. (Some scholars believe that Fu Sheng memorized the chapters instead of recovering them from the walls.)
