Why did Kublai Khan choose Beijing as the capital to rule the world?

"You yan land, surrounded by dragon and tiger, the situation is magnificent. It connects Jianghuai in the south and Shuomo in the north, which is the treasure land of China. However, Kublai Khan's choice of Beijing as the capital to rule the world was also a last resort. The former Yanjing City was already in ruins in the war, and the reconstruction needed a lot of manpower and material resources, so he chose Beijing as the capital of ruling the world. After Kublai Khan called Khan in 1260, he renamed Kaiping City, which he built in 1256, as his economic and political construction center, which is what we call the capital today.

Shangdu has a superior geographical position and unique advantages, but it is a battleground for military strategists and meets all the elements of the capital. However, Kublai Khan's ambition goes far beyond this. Although he has already sat on the throne, the emperor and remnants of the Southern Song Dynasty are still there. There is needle felt every day. Is orthodoxy important to Kublai Khan? We must destroy the Southern Song Dynasty, otherwise it will be difficult to sleep. After the demise of the Southern Song Dynasty was put on the agenda, we had to consider how to manage the recovered land. The Southern Song Dynasty has a vast territory, and the present capital is a bit remote.

After careful consideration, Yanjing is the first choice, but the old Yanjing has long been ruined, so we have to give up the old city of Zhongdu and build a new capital. The address is Qionghua Island in the northeast suburb, which is our early Beijing.
