Occupy Central with Love and Peace
From 2013, Tai launched and is known for his initiation of the Occupy Central with Love and Peace, as he considered Hong Kong to lack "true universal suffrage" and should participate in an Occupy movement to win universal suffrage in the 2017 Hong Kong Chief Executive election. His suggestion ultimately resulted in the eruption of the Umbrella Movement the following year, as a result of which he was found guilty of "conspiracy to commit public nuisance" and "inciting others to commit public nuisance" and sentenced to six months in prison. Citing this conviction, in July 2020, the University of Hong Kong's governing council controversially fired Tai.
