Southerners and northerners have obvious psychological differences, and people in different regions also have different personalities, which is closely related to the environment. Most northerners are bold, enthusiastic and extroverted; Southerners, on the other hand, are more delicate, steady, introverted and calculating. The reason for this difference is not because of the difference in brain structure or genetic factors between southerners and northerners, but because of the different geographical environment of life. In the north of China, there are fewer mountains and more plains. Looking around, you can see Fiona Fang for miles or even hundreds of miles. So northerners are more open-minded and generous. On the contrary, in the south, there are fewer plains than mountains and rivers, and the topography is blocked by mountains and rivers, which is quite broken. Only now the plains are criss-crossed, surrounded by mountains, and the vision is confined in a narrow space. Southerners plough intensively on palm-sized land. In order to survive, they have developed a cautious thinking habit and are good at using existing resources to exert their intelligence. In addition, the climate difference between the north and the south has caused the psychological difference between the north and the south. The climate in the south is mild and humid, and all kinds of flowers and plants compete with each other, making southerners calm, peaceful, emotional and delicate. The climate in the north is cold and dry, windy and dusty, with frost and snow in the past six months. Therefore, people who have lived in the north for a long time have formed a calm, childlike and virtuous character. Some environmental meteorologists have also demonstrated the influence of geographical environment on psychology and personality from another logic. They think that because of the vast territory and sparse population, mountain residents have developed a character of loud voice, straightforward speaking and sincere treatment. Therefore, they have the saying that "people love mountains". The warm and humid coastal areas of rivers and lakes are full of vitality because of the humid climate and beautiful scenery. Therefore, the residents here are often sentimental and resourceful, so there is a saying that "love the water is wise". Due to the vast grassland and inconvenient transportation, the herdsmen living on the vast grassland of the factory are generous and hospitable. In cold areas, due to the lack of outdoor activities, people often get along with others in a narrow space, so they often have strong endurance and self-control. Eskimos living in the coldest place on earth have amazing control and are called "people who never get angry" in the world. On the contrary, people living in some parts of the tropical region often live and work outdoors in order to avoid the heat. Coupled with their backward culture and education, they are often bohemian and often fight for small things. It can be seen that the influence of geographical environment on people's psychology and personality is not a duck meeting-nonsense!
