He is most known for initiating the Occupy Central with Love and Peace campaign, a movement to exert pressure on Chinese government officials to allow equal and universal suffrage in Hong Kong. The movement derives its authority and direction from Hong Kong’s Basic Law Article 45, a constitutional declaration and promise related to universal suffrage in electing the chief executive of Hong Kong. The establishment of this advocacy group has led to deliberative meetings, unofficial referendum, nonviolent occupations, civil disobedience, and demonstrations to combat Beijing’s imposed policies towards the territory. The Occupy Central movement took large part in supporting and demonstrating during the Umbrella Revolution.
