Hong Kong’s protests began in June 2019 against government plans to amend existing legislation and grant extradition to mainland China. Anti-government demonstrations had called for millions of people on street, followed by violent clashes between youth-led pro-democracy groups and police. Although the Chief Executive of Hong Kong Carrie Lam announced withdrawal of the bill in September 2019, protests continued to gather momentum in the following six months, escalated in scale, frequency and size and marked the biggest outbreak of social movement in the city’s history. During the half year of intense and frequent demonstrations, protesters mobilised a spectrum of demonstration methods, ranging from occupying the Government building, the use of lennon walls, human-chained rallies, acts of civil disobedience and street protests. They encountered police’s countermeasures and deployment of a vast array of weapons including live bullets, tear gases and water cannons. The movement caught the stiffest attention of students when battles were brought into Universities’ campuses, where petrol bombs were used by the activists against the police’s full siege of the colleges. More than ten thousands were arrested in the movement’s time span and protesters’ demands had further broadened to full democracy, inquiry into police actions, and amnesty of arrested protesters. Social unrest continued in 2020 and onwards.
