上海法租界
Over 20,000 Jewish refugees, including over 400 Jewish doctors and dentists (such as Rosenfeld and Richard Frey), around this time period fled to Shanghai, which was an asylum destination of last resort and later became the site of the Shanghai Ghetto. After release from the camp, Rosenfeld and his brother immediately requested visas from the Chinese legation and travelled to Shanghai, where he arrived in August, receiving visas from Ho Feng-shan. Once in Shanghai he opened a successful practice in urology, gynecology and obstetrics, in the Shanghai French Concession sector of the city.
