One of the great military texts from ancient China is The Art of War, believed to have been written in the sixth century BCE by Sun Tzu. The book, consisting of thirteen chapters, is still regarded by military planners as a definitive book on military strategy—particularly on how to win a battle or war without actually fighting but rather by outsmarting the enemy. The book continues to be required reading for officers in Asian militaries. Many of the book’s statements have become proverbial.
