What is history: it is the echo of the past to the future, the reflection of the future on the past. - Hugo
The Northern Song Dynasty, from the Song Taizu Zhao Kuangyin Chen Qiao mutinied into a yellow robe, from prosperity to decline until its demise, only 167 years, and the reason for the fall of the country was for a long time by Wang Anshi alone.
Many people believe that it was precisely because of Wang Anshi's change of law that the infighting in the Northern Song Dynasty continued, so that the originally good political atmosphere was wiped out, and a super mentally handicapped leadership group composed of Song Huizong, Cai Jing, Tong Guan, and others was formed, and came up with a completely mentally retarded decision to unite Jin and destroy the Liao, which led to the difficulty of Jingkang.

A poem by Yue Fei, a famous anti-Jin general of the Southern Song Dynasty, "Man Jiang Hong", which has "Jing Kang shame, Ju Wei Xue." When will the courtiers hate, when will they be extinguished? So how miserable is the "shame of Jingkang"?
The Jin people ordered the monarchs of the Northern Song Dynasty to face the north and bow down to the subjects. Emperor Qinzong of Song was so humiliated that he could only silently hold back tears, walked to the Gate of Nanxun in a daze, and saw that the courtiers and the people were waiting for themselves at the city gate, and the humiliation spewed out, and they actually cried loudly. There was a tremendous cry inside and outside the court.
The Jin people also asked the Northern Song Dynasty to hand over 10 million ingots of gold, 20 million ingots of silver, 10 million horses and mules and horses, but the Northern Song Dynasty at that time could not prepare so much money in a short period of time, and could only rob the rich merchants and magnates everywhere. The most difficult thing to assemble was the horses, only about seven thousand horses were put together, and the horses in the capital were empty, and the officials could only walk up the court
Even so, the amount demanded by the gold people is still far from the difference, and the gold people say that it does not matter if they are not together, they can use women to pay off the debt. Turn over fifteen hundred women, Song Qinzong did not dare to be sloppy, hurry up, and finally the women were not enough, so they gave all their concubines to the Jin people. These young girls could not bear this humiliation, and many people committed suicide.
Even so, the Jin people still intensified their demand for more money, Song Qinzong really couldn't get it, the Jin people asked Song Qinzong to come to Jinying himself to apologize, since Song Qinzong went to Jinying, the wind and snow in the capital city were not stopped, the people had no food, they could only eat leaves and cats and dogs, and finally they could only eat hunger and hunger, plus the spread of the plague, countless dead
In the second year of Jing Kang, Emperor Huizong of Song was also forced to go to Jinying, and on April 1 of the same year, the Jin soldiers divided into two routes and escorted Song Huizong and Song Qinzong, as well as the imperial family, harem concubines, civil and military ministers, craftsmen and people, no less than 100,000 people to the north.
The "Jing Kang Barnyard History Certificate" is very detailed in the record of this national disaster, because the record in the book is very humiliating, the correct history can not be recorded, so the reference value is quite high.
On July 20, Song Huizong and Song Qinzong's father and son met in Yanjing City, holding their heads and crying, but it had long been to no avail, and the Jin people gave Song Huizong the title of "Duke of Xiade" and Song Qinzong the title of "Marquis of Heavy Darkness"
In the north, the father and son were tortured, Song Huizong died at the age of fifty-four, Song Qinzong continued to be tortured, and finally died tragically in the north.
