On June 5, a man blocked the forward advance of a People's Liberation Army tank convoy on Beijing's Chang'an Avenue. According to reports, the man climbed onto the tank, talked to a soldier, and shouted, "Turn around! Stop killing my fellow citizens!" He was then taken away from the scene by three people. The process was captured by many news photographers and foreign media, including Charlie Cole, Jeff Widener, and others. Soon, photos and video of the 'Tank Man' were being widely circulated and discussed on the front pages of major international newspapers and news media. The photo became one of the iconic photos of the 1989 democracy movement, and won the 1990 World Press Photo Award. To this day, the real name, identity, and fate of the Tank Man remain unresolved. Many current Chinese media call him "Wang Weilin" (王維林/王维林), but this is based on the romanized name "Wang Weilin" that appeared first in the UK's "Sunday Express" tabloid. The documentary "Fly, Flag of the Republic," produced by China's August First Film Studio (attached to the People's Liberation Army), dubbed the man an "a miscreant blocking vehicles, like a mantis trying to stand against a chariot".
