Why do Zhenjiang people discriminate against Yangzhou people?

If you surf the Internet frequently, you can often see some Yangzhou people with the ID of "Yangzhou Goose" or "Slender West Lake" posting for a long time, which is nothing more than "Zhenjiang people are not as good as Yangzhou people", "Zhenjiang is poor, not as rich as Yangzhou" and "Zhenjiang is slow to develop and not as fast as Yangzhou". Stir up contradictions.

Of course, you can also say that these people are a minority, not the majority of Yangzhou people.

Then I can also say that the Zhenjiang people you see cursing Yangzhou people are also a minority, which does not represent most Zhenjiang people.

Nowadays, people are generally impetuous and lack tolerance, and they should scold things they don't like, even if they don't hurt themselves. Besides, regional disputes have existed in China since ancient times, which is also a bad habit of China people. The specific performance can be seen from my two answers above.
