In the Shaoxing period of the Southern Song Dynasty (the period of peace and war between the Song and Jin Dynasties), Princess Wanyan Jingyue of Lanling of the Jin Dynasty (the sister of Jin Xizong, who understood Sinology and had political sensitivity, and was actually the proton of the Jin Dynasty) entered the Song Dynasty and became acquainted with Su Yanchen, the first-rank left prime minister who came from a poor family and dominated the government and the public because of the "Song-Jin Peace Talks". The two fell deeply in love, but due to the pressure from the Jin Kingdom's war faction (Jingyue's mother's family was placed under house arrest) and the Song Dynasty's "Tong Jin" impeachment (Yan Chen's political enemies framed it), in the end, in order to protect the family and the country, they went from "love under the moon" to "confrontation on the battlefield", and finally broke up forever. Those who like to read sadistic stories can also come up with ideas to see what kind of suffering they will have to endure. We will turn it into a plot to let them go through more hardships.
