When Mongolia was destroyed, why did Jin Guo run to Henan without returning to his hometown in Northeast China?

After being used to the rich life of the Central Plains, the Golden State was obviously reluctant to return to the cold Northeast hometown to live the life of the fishing and hunting people. In 1214, Jin Xuanzong, the eighth emperor of the Jin Dynasty, was forced by Mongolia, and led the crowd to move the capital to Jingjing (now Kaifeng).
The second year, Mongolia broke the original capital of the Golden State, Zhongjing Dading Mansion (also known as Daxingfu). After losing Central Beijing, the northeast hometown and the Central Plains region of Jin Guo have been cut into two sections.
The capital Yu Jingjing has explained that the Emperor Jin of the Kingdom has abandoned the northeast hometown of the ancestors of the ancestors, and chose the prosperous Central Plains region. After all, the wealth of the Central Plains has deeply attracted the Golden State, so that they have refused to return to the fish and hunting life of the sunrise and sunset. However, he didn't know that in the next 20 years, the Central Plains will also become broken due to the violent invasion of the Mongolian cavalry.
The Jin Xuanzong Wan Yan Yan was the eighth emperor of Jin Guo. When he was in office, the Jin Guo had declined. The strong enemy Mongolia gradually emerged. Before 1999, Jin Xuanzong's ancestors, the founding emperor of Jin Guo, called the Emperor of the Northeast Huining Mansion in the Northeast, and established a strong Jin Guo.
women are really insufficient. Shortly after the establishment of the Jin State, the Liao Dynasty and the Northern Song Dynasty were successively eliminated, and the Southern Song Dynasty could not move south of the Huaihe River. Although Jin Guo's invasion of the Southern Song Dynasty failed, he was always in the position of active attack and forced the Southern Song Dynasty to sign the humiliated "Heavenly Family Heaven", "Shaoxing Peace", "Longxing Peace", "Jiading peace".
The Southern Song Dynasty even ignored the humiliation of Jingkang's difficulties, and repeatedly called Jin Guo Na Gong, and accepted the condition of killing Yue Fei. It can be seen that Jin Guo's strength was very strong at the time.
But over time, the inside of the Kingdom has gradually moved towards decay. The original female true cavalry who was brave and good at indulged in the lively and rich life of the Central Plains, and the combat effectiveness declined rapidly. The ruling class of the Golden State was also decaying from generation to generation. It was only satisfied with the tribute to accepting the Southern Song Dynasty, and lost the ambitions of the ancestors to open up the territory.
In 1206, Mongolian Tiemuzhen unified the Mongolian Plateau. Mongolia and the Golden State (female true tribe) originally had old revenge, so the attack on the attack was aimed at Jin Guo. However, although the Golden State is very corrupt, the overall strength is still stronger than that of Mongolia. It did not decide until the war in the Wildhu Ridge in 1211 AD. The 400,000 army of Jin Guo lost his losses in the battle of the Wo Ling and completely lost his power to compete with the Mongolian army.
Waiting until Jin Xuanzong's succession, the national situation of the Kingdom of Kim is increasingly declining, but Mongolia has risen like a new sun, and the comparison of the strength of the two countries has completely changed. Jin Xuanzong had to face a serious problem. If the Great Wall's defense line can't hold it, is it returning to his hometown in Northeast China? Or do you go south to operate the Central Plains?
Obviously, the Golden State Noble Group, headed by Jin Xuanzong, used to live a rich and beautiful life of the Central Plains, and can no longer adapt to the bitter cold life of the Northeast jungle like the ancestor Kim Taizu and Jin Taizong, and many Jin Guo nobles also also Unwilling to return to his hometown in Northeast China. However, they asked Jin Xuanzong to adhere to Zhongdu Daxingfu.
In 1214, Jin Xuanzong relied on the opposition of the ministers, and moved the capital from China (Central Capital) to Kaifeng Mansion in Nanjing (formerly the Capital of the Northern Song Dynasty). This marks that the political center of the Kingdom is difficult to move and loses the management of the Northeast. In the second year, the main force of the Mongolian army crossed the Great Wall to surround the Golden Ding Dingfu Mansion. Because the emperor had already escaped, the morale of the army was low, and he insisted on adhering to the city.
P. After the main force of Mongolia broke through the Kim Junior High School, there was a trend of further south. The Emperor Jin Xuanzong of the Kingdom of Jin Guo learned the old road of Song Huizong decades ago and paid the princess to the Mongolian land. sleep. Jin Xuanzong was anxious to seek peace with Mongolia and presented Princess Qi.
"Golden History" records that the Mongols got Princess Qi Yan Yan's (later married to Genghis Khan as a concubine) from Jin Xuanzong, and carried 500 boys and girls with Gonggong Gong, embroidered clothes The countless gold and silver jewelry in the Golden Kingdom Palace returned with 3,000 sets, 3,000 horses, and the Golden Kingdom Palace.
but Jin Xuanzong did not cheer up after he fled to Jingjing, but struggled with one side. His foreign policy has also made many mistakes, and war broke out with the Southern Song Dynasty and Xixia, which made the weakened Golden State situation worse. During the reign of Jin Xuanzong, Jin Guo gave up the northeast of Longxing and fled to Henan to cut the side, and he died of illness in Henan.

Mongolia was involved in the rear of the Kingdom, so it could only escape south, instead of running away from the northeast.
