This short, ancient classic by an unknown (but obviously brilliant) Chinese general on military strategy is eye opening and shockingly enduring as a work.
Why pick this translation over the many that are available on the market? Because it has been translated by Chinese people themselves who are better equipped to read and translate the subtle nuances in the work that would go over the heads of the many Europeans who have attempted to translate this work.
I picked it up many years ago from a Chinese shop in Holland just after first graduating. I found it again after years when I was going through some old boxes and scanned it. I tried sticking it on my scribd with no success, but you can download it for free from the link. I hope some of you learn a thing or two from it and enjoy studying it.
