What is the only city in China where Japanese are forbidden to enter?

The only city in China that explicitly forbids Japanese to enter is Lushun. Lushunkou District belongs to Dalian, Liaoning Province, and is located at the southernmost tip of Liaodong Peninsula.

This ban is related to Japan's invasion of China in history, especially the Lushun massacre in Lushun, which left a deep painful memory for the local people. Therefore, Lushun clearly marked the words "Japanese are forbidden to enter" in some public occasions to express his unforgettable memory of the history of Japanese aggression and cherish peace.
