Yang Huimin (traditional Chinese: 楊惠敏; simplified Chinese: 杨惠敏; pinyin: Yáng Huìmǐn; March 6, 1915 – March 9, 1992) was a Girl Guide during the 1937 Battle of Shanghai who supplied a flag and brought supplies to besieged defenders of the Sihang Warehouse. Her actions proved inspiring to the defenders, who flew the flag the next daybreak in front of thousands of watching eyes across the bank of the Suzhou Creek.
