It has been dubbed the "Umbrella Revolution." But that isn't the only symbol to come out of Hong Kong's pro-democracy protests.
Local artist Kacey Wong also explains the meaning of the yellow ribbons and numbers spotted on signs.
He believes there is a lot at stake during this demonstration for universal suffrage.
"Right now I can see this war on culture. The winners will get to keep their way of life and their culture. And if you lose in this war, we have to fall back," Wong says. "We donâ€™t want to fall back into the chaos that we read in the news from mainland China. I think it is time for mainland government officials to learn that if they want to join the international community, they have to behave in a civilized way. And this is a golden opportunity."
