Chinese war heroine, Ynghui Min emerges while Japanese Navy and Air Force attack in Kiukang, China (1938) Yang Hui-min's action in delivering a national flag to Republic of China troops who were besieged by Japanese forces at a Shanghai warehouse in 1937 was driven by patriotism and bravery. Yang, born in 1915, became a civilian heroine during the Second Sino-Japanese War from 1937 to 1945 when she braved grave danger to deliver the flag to about 400 besieged soldiers who were holding out at the Sihang Warehouse during the Battle of Shanghai. The Battle of Shanghai, which erupted on Aug. 13, 1937, disrupted Japan's plan to seize China within three months. About 400 Chinese soldiers held out at the Sihang Warehouse for four days and nights in October that year, allowing most of the other troops to retreat to the west and carry on the fight against the Japanese Imperial Army.
