Hong Kong young activists are no greenhorns when it comes to protests. As another huge rally is organized for Sunday, protesters’ strategies are getting more creative. From hand signs to colorful post-it notes, these young activists have fine-tuned their tactics since the 2014 Occupy Central pro-democracy demonstrations

Hong Kong pro-democracy activists have honed diverse ways of expression and tools to optimize efficiency, and to resist and protect from police violence to keep up the momentum, after more than a month-long of protests.

Facemasks, goggles, and helmets are worn to protect from pepper sprays. Others wear raincoats and carry different tools. If yellow umbrellas were the iconic symbol during the 2014 demonstrations, hardhats—the yellow and white protective helmets—make a statement this year.
