Hand signals and shields: how Hong Kong's parliament was stormed

With makeshift shields zip-tied to their wrists, a trolley converted into a battering ram and rehearsed hand signals, Hong Kong's protesters showed remarkable levels of do-it-yourself savvy as they besieged the city's parliament. Many of the current generation of largely young protesters proudly repeat the phrase "be like water", a philosophy of adaptability and unpredictability espoused by martial arts master and local legend Bruce Lee. The equipment is then ferried to the front by long, snaking lines of protesters.
