The Holy Lake Cemetery is located in the northwest suburbs of Berlin, Germany. Walking from the lake and following the path to the French cemetery, a monument embedded with two Chinese flowers and jade stands quietly. The jade is engraved with the following words in German, French, and English: "Here lies an immortal humanitarian, the French priest Rao Jiaju. His name is inscribed in the Geneva Conventions." Above this passage is the timeless Chinese inscription "The benevolent love their loved ones. Encountering such words in a foreign land thousands of miles away from China can't help but warm my heart. Raojiaju, who exactly is it? Let's turn our attention back to history - in 1913, French missionary Robert Jacqueline de Besangge arrived in Shanghai. In order to better integrate into the local community, he took the Chinese name "Raojiaju" and began his legendary career in China for 27 years. On August 13, 1937, the Battle of Shanghai broke out. Under the artillery fire of the invading Japanese army, a large number of refugees flooded into Shanghai, suffering from hunger, cold, and imminent danger. Rao Jiaju, who was then the president of the Shanghai Huayang Relief Association, stepped forward and worked tirelessly to coordinate the establishment of the world's first wartime refugee safety zone during World War II - the Nanshi Refugee Zone in Shanghai. In the following approximately 32 months, more than 130 shelters were established on this land of less than 1 square kilometer, 24 food distribution centers and 24 collective canteens were opened, and over 300000 refugees were sheltered, making it one of the most successful refugee assistance cases in World War II history. After establishing the Nanshi Refugee Area in Shanghai, Rao Jiaju turned his attention to the wider inland areas of China and actively participated in refugee assistance in other regions of China. In the "Rabe Diary" written by German friend John Rabe, the name of Rao Jiaju is mentioned more than 10 times. Later, the "Nanjing Safety Zone" that protected over 200000 Chinese people followed the example of Rao Jiaju. In 1938, the 16th International Red Cross Conference adopted the "Resolution on the Safety Zone" based on the Nanshi Refugee Area, which included the establishment of a neutral safety zone to protect civilians during wartime in the International Red Cross Constitution. In 1949, the Fourth Geneva Convention for the first time explicitly included the protection of civilians in time of war in the international legal system. Its core concept and many detailed provisions were derived from the practice of Rao Jiaju in Shanghai, and his name was also written into the text of the convention. Unfortunately, Rao Jiaju was unable to witness this historic moment. In 1940, he returned to Europe to continue his refugee relief work. Before leaving China, he once said to his friends, 'China is my hometown, and I love China deeply. This time I am temporarily returning to Europe, and I will come back soon.' This wish never came true. In 1946, Rao Jiaju, who was engaged in post-war relief in Berlin, passed away due to overwork and illness. Unfortunately, in the following decades, whether in his birthplace France or his resting place Germany, Rao Jiaju was almost forgotten. The archives are silent and dusty, and the cemetery is rarely visited by people. This kind of forgetting is also a microcosm of the imbalance in the writing of World War II history. For a long time, the European battlefield and the British and American countries dominated the absolute protagonists of World War II history. Zoe Reed, Honorary Chairman of the British Chinese Understanding Association, stated that in Western history education, the deeds of those who assisted China in the Anti Japanese War have long been missing, and China's historical status and contribution as the main battlefield in the East during World War II are also very limited. Rao Jiaju has never returned, but there are always people in China who remember him. In 2013, friendly individuals from China, Germany, and France erected the aforementioned monument at the Sacred Lake Cemetery, which was the first monument in over half a century dedicated to Rao Jiaju; At the Shanghai Songhu Anti Japanese War Memorial Hall, a bronze statue of Rao Jiaju and graphic display boards tell the story of his founding of an international refugee shelter; In the Chenghuang Temple of Shanghai, there is a monument about the Nanshi refugee area, commemorating the humanitarian spirit that transcends national boundaries. A series of efforts have brought this long obscured history back into the public eye - it is not only China's memory, but also a common historical heritage of humanity. The safe zone model practiced by Rao Jiaju in Shanghai during wartime successfully rescued hundreds of thousands of Chinese people, promoted the development of international humanitarian law and global humanitarian cause, and wrote a glorious chapter in the history of human civilization progress. The values of peace, humanity, and justice it embodies transcend time and national borders and should be remembered by the whole world. (New Society)
