The South of China was lush and misty, compared to the North's arid, windy plains. There was a warm temperature and plenty of rainfall.

The city of Hangzhou is still there today, and so is the city of Guangzhou, as you can see on the Present Day China map. On the Southern Song Dynasty map, the thick black line shows where the border of the dynasty is. The dotted line is the Yangzi River.
