Methods of the Minister of War

The Simafa "Methods of the Minister of War" is an ancient book on military strategy. It belongs to the corpus of the Seven Military Classics (Wujing qishu). It is attributed to Sima Rangju, a general of the state of Qi during the Warring States period (5th cent.-221 BCE). The book is therefore also known under the title of Sima Rangju bingfa or Sima Bingfa.
