Which is higher, Shanghai IQ or Yangzhou IQ?

Shanghai is an immigrant city. Although there are people from all over the country, it is an indisputable fact that there are the most people in Jiangsu and Zhejiang provinces. Immigrants are divided into two categories. One is the smart people among the rich. They are not willing to be rich in the countryside, but choose to set up factories in Shanghai. Many Shanghai national capitalists are their representatives. The other is the smart people among the poor. When their livelihood is difficult in their hometown, they don't choose to die in their hometown, but choose to go to Shanghai to explore the world. Skilled craftsmen in many industries are their representatives, while some people who are not smart enough either have to leave Shanghai at a loss in business, or they can't survive in Shanghai because they are not skilled. Those who can finally stay in Shanghai are all smart people. Decades have passed, and the descendants of these Shanghainese, or descendants of their descendants, continue to contribute to the development and prosperity of Shanghai. Of course, more and more local people have become new Shanghainese, and they are also smart people in the new era. As for Yangzhou people, there are three knives in old Shanghai, namely, kitchen knife, shaving knife and pedicure knife. They are arrogant in these three fields, but as for other industries, they are not new.
