Does anyone have a high-resolution picture of this map?

I found a map that supports online enlargement and contains maps of different years. You can check it out. Here is a screenshot:

The Southern Song Dynasty (1130-1309) was the period after the fall of the Northern Song Dynasty. , the Song Dynasty moved south and established a political power in the south of the Yangtze River. It was a dynasty with developed economy, cultural prosperity and scientific and technological progress in Chinese history. Nine emperors lived in the country for 152 years.

Although the Southern Song Dynasty was located south of the Qinling Mountains and the Huaihe River, it was a dynasty with the most developed economy, ancient science and technology development, foreign trade, and high degree of openness to the outside world in Chinese history. The Southern Song Dynasty coexisted with the Jin Kingdom, Western Liao Dynasty, Dali, Xixia, Tubo and the Great Mongolia that emerged in the early 13th century. The devastating blow to the advanced production relations of the Song Dynasty by the nomads caused the advanced Eastern civilization, which had been on the rise, to gradually turn to decline and eventually fall behind the world's mainstream stage.
