Song Dynasty is a dynasty in the history of China, which inherited five dynasties and ten countries and initiated the Yuan Dynasty. It is divided into two stages: Northern Song Dynasty and Southern Song Dynasty. It lasted 18 emperor and enjoyed the country for 3 19 years. The Song Dynasty was an era of high prosperity in commodity economy, culture, education and scientific innovation in the history of China. The Song Dynasty was founded more than 300 years ago and was overthrown twice, both because of foreign invasion. This is the only dynasty that did not die of civil strife. The dynasties of the Song Dynasty are also very strange. The northern song dynasty chose the wrong capital, and the southern song dynasty had no capital.

The Northern Song Dynasty ended the war in the Five Dynasties and Ten Countries after the Tang Dynasty, unified the country and started economic construction. Everything was not satisfactory. Song Taizu wanted to move the capital and proposed to move it to Luoyang, but it was opposed by dignitaries. In order to restore the economy, the Song Dynasty encouraged and connived the dignitaries to do business, which led most of them to have huge economic interests in the capital of song dynasty. However, Zhao Guangyi was worried that he might not become an emperor after moving to Luoyang, so he didn't move the capital, and then he chose the wrong capital. We should know that Kaifeng is a typical "land of four wars" and it is very unfavorable to be the capital of a country. Although the heavy garrison can make up for the defects, I know that the strength of the Song Dynasty is a paper tiger.

Luoyang is bordered by Mangshan Mountain in the north, Que in the south, and Luoshui runs through it. Hulao Pass is in the east and Hanguguan is in the west. The geographical danger should be conducive to defense. Although Luoyang City built in Sui and Tang Dynasties is very shabby, it can be solved through construction. Much better than Kaifeng. But the Northern Song Dynasty chose the wrong capital, which led to the demise of the Northern Song Dynasty.

In the Southern Song Dynasty, Hangzhou was promoted to Lin 'an Prefecture and Jiankang Prefecture remained as the capital, indicating that our country still had a reserve capital, which supported its own face and dared not admit to running away. Moreover, in order to show the determination to recover their homeland and return to the Central Plains, there was no capital in the entire Southern Song Dynasty.
