Ancestor Hunt has published World War ll era Shanghai newspapers online. Shanghai became a haven for fleeing Jews during World War ll because of their lenient visa requirements and they accepted thousands of Jewish refugees.
While the Shanghai Jewish Refugee Museum built a database that contained the name, occupation and address for many of the refugees, that database is no longer available. It might be found by using the Way Back Machine ( Internet Archive) . If you do find it on their please share that with JGS Toronto
However, there are some Shanghai newspapers written by and for Jews that were digitized and are available online. Some are in English and most are in German. Best to look at both Internet Archive (https://archive.org/) and the Leo Baeck Institute (https://www.lbi.org/) .
The article in Ancestor Hunt has 10 links to newspapers: https://tinyurl.com/yakasps2
