Which place has a better economy, Yangzhou, Suzhou or Changzhou?

Suzhou: the most popular city in Jiangsu. GDP is scary. It calls itself the back garden of Shanghai. Consider all places outside Shanghai and Suzhou as poverty-stricken areas. Citizens are proud to work as assembly line workers in foreign-funded enterprises, and their products do not even have Chinese logos. Crazy extraction of groundwater for economic indicators has resulted in serious surface subsidence. There is a serious water shortage, but we still have the nerve to say that we are a water town.

Changzhou: a "big city" that no one knows outside of Jiangsu. Recently, I am considering developing into a megacity. The industrial base is not bad, another potential source of pollution. Because they can't escape the shadow of Suzhou and Wuxi, they particularly look down on people from Jiangbei, but it is said that they are about to be overtaken by Nantong.

Yangzhou: the birthplace of northern Jiangsu culture. He often says he is Jiangnan without conscience. A "famous historical and cultural city" that can be seen in one day. Rumor has it that beauty is actually a pedicure master and a back rub. Now, thanks to a certain leader, a large-scale construction project has begun. Citizens tell everyone they meet that Yangzhou is now a big city too.
