Because Jackie Chan took a photo in front of a coffee shop in Germany and walked through that street. Jackie Chan's fame and influence can be said to have legions of fans all over the world. How crazy foreign fans are when Jackie Chan attends overseas events. Every time I go out, I need more than a dozen bodyguards. In foreign countries, there is not only "Jackie Chan Day" commemorating Jackie Chan's name, but there is also a commercial street called "Jackie Chan Street" in Germany. It is said that in Germany, only great people who have passed away a hundred years have such an opportunity to name a street after a person. And this street was named just because Jackie Chan took a photo in front of a coffee shop in Germany and walked through that street.
