Feng-Shan Ho, the Consul General of China in Vienna between 1938 and 1940, acted contrary to his instructions and unlike most other diplomats, and issued entry visas into Shanghai to Jews who requested them. Most of the foreign consulates denied Jews' requests for immigration visas.
In November 1938 after the Kristallnacht pogrom, thousands of Jews were imprisoned in concentration camps. Their release was conditional on their leaving Austria immediately, which necessitated having an entry permit to another country. This resulted in a sharp increase in the number of requests for entry into China.
