Thinking about all this from the angle of historical geography, I think northerners are used to being ruled by nomadic tribes, and the physical environment makes northerners more open-minded; southerners, on the other hand, are the stubborn guardians of Chinese cultural traditions, so to speak, they opened up the south when they fled there to escape foreign domination, so they have a strong "spirit of resistance."
這樣的現象，從歷史地理學角度來思索，我想中國北方一直有遊牧民族統治的經驗，而且北方人受地理環境影響性格較豪邁開闊；而南方人，可以說是堅持保衛中國文化傳統，不甘心受異族統治而逃往南方的開拓者，有很強的「抵抗精神」。
