孙武
In 1972, circumstantial evidence unearthed from the number one grave at Yinque Mountain, Linyi Prefecture, Shandong Province provided Han Dynasty bamboo slips inscribed with "The Art of War" by Sun Tzu. The historian Li Ling mentions this in his simplified version "Sun Tzu" in the "Espionage" chapter, viz "When the Zhou flourished, Lu Ya was in Yin" followed by the sentence, "When Yan flourished, Su Qin was in Qi". Li Ling believes that this "Sun Tzu" is not the same as the one handed down to later generations and is clearly the history of the late Warring States period.
