Why is "Shanghai Ghetto" trending?

Wikipedia Overview

The Shanghai Ghetto, formally known as the Restricted Sector for Stateless Refugees, was an area of approximately 2.5 square kilometres in the Hongkou district of Japanese-occupied Shanghai. The area included the community around the Ohel Moshe Synagogue. Shanghai was notable for a long period as the only place in the world that unconditionally offered refuge for Jews escaping from the Nazis. According to the Simon Wiesenthal Center, a leading authority on the Holocaust, Shanghai accepted more Jewish refugees than Canada, Australia, New Zealand, South Africa and India. After the Japanese occupied all of Shanghai in 1941, the Japanese army forced about 23,000 of the city's Jewish refugees to be restricted or relocated to the Shanghai Ghetto until 1945 by the Proclamation Concerning Restriction of Residence and Business of Stateless Refugees. It was one of the poorest and most crowded areas of the city. Local Jewish families and American Jewish charities aided them with shelter, food, and clothing. The Japanese authorities increasingly stepped up restrictions, surrounded the ghetto with barbed wire, and the local Chinese residents, whose living conditions were often as bad, did not leave. By 21 August 1941, the Japanese government closed Shanghai to Jewish immigration.
