Dü sseldorf, the capital of North Rhine-westfalen, was severely damaged in World War II, but now it has a strong development momentum and good contacts with China. However, it may be difficult to directly compare with a city in China, because the social, economic and cultural backgrounds of the two countries are different.

But in terms of population size and economic development, Dusseldorf can be compared with Shanghai in China to some extent. Shanghai is the economic and financial center of China, similar to Dü sseldorf's position in German. However, it should be noted that this comparison is not completely accurate, because the environment and background of the two cities are very different.
