Why are there many Germans living in Shanghai?

This question is a bit difficult, because Shanghai is an international metropolis, and it is normal to have some foreigners. As for why there are more Germans, it may be that this city is more attractive to Germans. What is the first impression we Chinese have of Germans? Thomas Muller, Nowitzki... The Germans give us the impression that they are more rigorous, the Germans are very intelligent, and the entire nation can be called one of the better nations. Germany and Japan were the main culprits in World War II at the same time, but their attitudes towards the war were completely different, which is one of the reasons why the Germans are more popular. Generally speaking, our impression of the Germans is relatively good. There is no discrimination among the people, so some Germans are willing to come to our country to bring advanced technology, management experience, etc. to enjoy the fruits of development. I think a large part of the reason why Germans gather in Shanghai is due to job transfers. Shanghai can be said to be the leader of China's economy, and many foreign companies have set up subsidiaries in Shanghai. Especially in some fields that Germany is good at, such as machinery, automobiles and other industries. When I was interning at a foreign company in Shanghai last semester, I saw many Germans. They usually serve as technical guides to provide training and guidance to Chinese technical workers. Or they may directly be the leader and be in charge of all aspects of the Chinese company. These are very common. Another thing is that Shanghai's development is better than other cities, which means better study and work opportunities for some Germans, so they usually gather here. There will be some foreigners in every city, such as Guangzhou, Hangzhou and other eastern cities. This also reflects the achievements of our country's economic development and shows China's changes to the world.
