Zong Ze (1059-1128), a famous general of the Northern Song Dynasty (960-1127), was familiar with military strategy and tactics and made some fine achievements in his official career. He died full of worries and indignation when his nation was defeated by invaders. Zong was honored with the posthumous title of "Zhongjian" which means loyalty in Chinese. The book called Collected Works of Zong Zhongjian has been passed down the generations.
