Three-finger salute (pro-democracy)
The three-finger salute is a hand gesture made by raising the index, middle and ring fingers, while holding the thumb to the little finger, and raising the hand with the palm facing out in a salute. The gesture was popularized in the 2010s after its use in The Hunger Games as a symbol of revolution.
