沈括是北宋一位出色的爱国者。他立足于“知己知彼，百战不殆”的军事古训，实地考察了党项、契丹的风土人情和“胡人”的城寨兵器，有针对性地解决了北宋国防战略中存在的具体问题。他创制出的木版立体图，鲜明逼真地展现出山川道路的自然形态和堡寨村落的位置，对西北战局的发展产生了极大的影响。 Shen Kuo was an outstanding patriot in the Northern Song Dynasty. Based on the ancient military doctrine of “Knowing Your Own Things We Must Know Everything,” He inspected the party items, the local customs and practices of the Khitan people and the weapons of the walled city of the “barbarians”, and specifically addressed the specific problems that existed in the strategy of national defense in the Northern Song Dynasty. He created a three-dimensional map of wooden plates, vividly demonstrated the natural form of the mountains and rivers and the location of the fortified village, which had a tremendous impact on the development of the Northwest Fight.
