My book review

In my opinion,the most effective strategy in Sunzi'art of war is "Planning before going to war".Because it is very important to compare and analyze all factors of both sides. These mainly include: morale ,climate, terrain, and rules.It's not easy to get to know the enemy, because they do their best to keep their secrets and resort to all sorts of deception.I like it very much. I learned how to deal with problem because of it.
