"In this Monday, July 1, 2019 photo, protesters use hand signals to gestures for scissors during their attempt to break into the Legislative building in Hong Kong. Protesters use hand signals to communicate which supplies need to be delivered to the front lines. Arms circling the head indicate ""helmets,"" while a forward cutting motion made by the index and middle fingers signals ""scissors."" The items are then passed through a human chain.
