Graffiti can also be used to voice opinions and dissatisfaction towards authorities. For instance, there was graffiti related to "real universal suffrage" being drawn in Admiralty during the Occupy Central protests in 2014. Individuals voiced their anger and depression towards both the Chinese and Hong Kong governments through graffiti work. They hoped to make common cause with Hong Kong citizens through graffiti art in order to gain more support for universal suffrage. For example, protesters not only did chalk paint graffiti, but also created a mural made from thousands of Post-It notes with citizens' wishes written on each. Couplets with citizens' petitions were also hung on a footbridge.
