A year ago, Hong Kong’s famously busy streets were shut down by pro-democracy activists who occupied them for 79 days in what became known as the "Umbrella Movement." The protests were led by students and other activists who took to the streets to voice their opposition against Beijing's plan to restrict elections for top leader of the semiautonomous Chinese city.
