The concept of traditional regional differentiation

The traditional geographical division of China is divided into north and south by Qinling Mountains and Huaihe River.

Qinling Mountain is the watershed between the Yellow River and the Yangtze River, so it is generally recognized that the Yangtze River basin is in the south and the Yellow River basin is in the north.

Region usually refers to a certain regional space, which is a synthesis of natural factors and human factors. Generally speaking, it has three characteristics: regional, humanistic and systematic. Different regions will form different mirrors, reflect different regional cultures and form a unique regional landscape. Such as China's north-south cultural landscape and Japanese earthquake-proof architectural design.
