To say why, let's talk about what Huanglong means first. Huanglong is actually a place name, Huanglongfu, which is the birthplace of Jin people. So who are the two saints? These two saints were the emperors of the Northern Song Dynasty, Song Huizong and Song Qinzong. This period of history has to be said to be a shame of the Song Dynasty.
In fact, the territory of the Jin people was not large, and even the Song Dynasty at that time did not attach importance to Daikin. Only later, it developed faster and faster until it grew into an empire. At that time, Liao was very noisy. In order to fight against the Liao Dynasty, the Emperor of the Northern Song Dynasty joined hands with Daikin to destroy Liao, which was also a stupid place in the Song Dynasty. Without the restriction of Liao country, Daikin naturally extended his talons to the Song Dynasty. The brave Jin people occupied Longcheng without blowing off dust and arrested two emperors in the Song Dynasty. In fact, it was not only two emperors who brought Daikin back, but also a group of royalty. Shouting this slogan, on the one hand, let the people of the Southern Song Dynasty know the emperor's filial piety, on the other hand, it is also to shock the Jin people and let them know the determination of the Song Dynasty to fight against the Jin people, which can be described as killing two birds with one stone. For Yue Fei, it is his long-cherished wish to rebel against the ruler and save Er Sheng. In his mind, he has always regarded this as his mission. He believes that the great country will not be defeated by the Jin people, and he also believes that one day he can go straight to Huanglong. But he never imagined that he would die at the hands of his family.
