首先,我们要了解当时辽宋两国的国情。综观宋朝军事,我们不难发现,宋从开国之初的积极进取到急于求胜,到屡战失利再到一味求和。宋在席卷南方以后,不费吹灰之力把北汉也灭了。然而,在与辽国的交战中却一再失利。第一次,宋太宗中箭乘驴车跑路。第二次,先是曹彬被耶律休哥和承天太后包夹,再是潘美逃跑,杨业被俘,最后宋太宗无奈修渠蓄水,防止辽骑南下。 First of all, we must understand the national conditions of the two countries at that time. Looking at the Song and Song dynasties, we can easily find out that since the founding of the People’s Republic of China, Song actively sought for success and went on to fight peacefully after losing defeat. Song swept the South, effortlessly destroyed the North Han also. However, it has repeatedly lost ground in the war with the Liao States. For the first time, Emperor Taizong used the donkey cart road. The second time, Cao Bin was the first lawyer Hugo brother and Cheng Tian empress inter-triad, and then Pan Mei escape, Yang industry was captured, and finally Song Taizong reluctantly repair canal water storage to prevent Liao riding south.
