The north-south dividing line of China lies in the north-south boundary bridge in Wei 'an City, Jiangsu Province. The Huaihe River in Qinling Mountains is the dividing line between north and south of China, and rice is planted and eaten south of Qinhuai River. It is obvious to all that China people on both sides of the Qinling Mountains and Huaihe River have a strong sense of north and south. It is always a hot topic of debate, from sweet tofu to the similarities and differences of national character. People in many countries will divide their countries into the south and the north, fill in the blanks and either belong to the south or regard themselves as northerners, such as Italy, Germany and the United States 50 years ago. When they are happy, the south laughs at the north, or the north teases the south, which is not malicious, but adds a lot of fun. If they really hate each other, they are likely to break up. For this kind of national psychology, we call it "North-South consciousness". The north-south boundary of these countries is mostly formed by historical habits, and there is no obvious physical and geographical boundary. However, China is an exception. A Qinling Mountain, which runs through the east and west, and the Huaihe River, one of the seven major water systems, naturally form the geographical dividing line (belt) between north and south in eastern China. Some scholars even extend the Qinling Mountains to the west, connecting them with Kunlun Mountain (including Mount Animaqing) or Qilian Mountain, and running the north-south dividing line through China.
