The heroic deeds of Yang Jiajiang, a very famous family in the Northern Song Dynasty, have been handed down to this day, and even many film and television works are telling the story of Yang Jiajiang's heroic service to the country. However, in the Northern Song Dynasty, facing the danger of extinction, Yang Jiajiang did not appear. This is because in the Northern Song Dynasty, Yang Jiajiang was actually famous only in the previous generation. Later, at the end of the Northern Song Dynasty, Yang Jiajiang had actually declined and did not have enough strength to save the country.

Yang Ye, the first 1 generation general of Yang Jiajiang, was loyal at first, but after the Northern Han Dynasty was defeated by the Northern Song Dynasty, Yang Ye took refuge in the Northern Song Dynasty and became a loyal minister for the Northern Song Dynasty. Yang Jiajiang was very famous when he first took refuge in the Northern Song Dynasty, because Yang Ye was a famous general in the Northern Han Dynasty with high martial arts. Therefore, after receiving the generals from Fuyang, the Northern Song Dynasty attached great importance to Yang Jiajiang and granted him important positions and great military power. Later, Yang Jiajiang was stationed in the border areas of the Northern Song Dynasty, and Song Taizu took back the military power of Yang Jiajiang in order to prevent the separatist regime.

After Yang Jiajiang had no relieving power, his power gradually lost, and the family of generals who once made a name for themselves in the Northern Song Dynasty declined. At that time, the power of the Song Dynasty was very concentrated, Yang Jiajiang was very neglected, and even some loyal generals were eliminated. From then on, Liang Jia will gradually fade out of history. In film and television works, some descriptions of Yang Jiajiang are actually exaggerated. In the real history, the Yang Jiajiang family had declined before the demise of the Northern Song Dynasty, and Yang Jiajiang, who had no right, could do nothing when he saw the decline of the country. In its heyday, Yang Jiajiang did make great contributions to the Northern Song Dynasty and fought in Liao.

When the Northern Song Dynasty was facing the catastrophe, Yang Jiajiang did not defend his country for fear of death, but because Yang Jiajiang's strength had been greatly weakened by the imperial court a long time ago, and there was nothing he could do in the face of family destruction. But Yang Jiajiang is still a commendable family of generals.
