Why is "Liberalism in Hong Kong" trending?

Wikipedia Overview

Liberalism in Hong Kong has become the driving force of the democratic movement since the 1980s which is mainly represented by the pro-democracy camp which strives for the universal suffrage, human rights and rule of law in Hong Kong. It is one of two major political ideologies of the Hong Kong, with the other being conservatism. The emergence of the contemporary liberalism took root in the rapid democratisation in the final years of the colonial years in the 1980s and 1990s, which the pro-democracy camp was united under the banner of an autonomous Hong Kong under Chinese sovereignty. The liberals consolidated their popular support from the 1989 Tiananmen Square protests and massacre and received landslide victories in the first direct elections in 1991 and 1995 in the final colonial years. The liberals took the defensive role against the Beijing's authoritarian regime going into the early SAR period which led to the massive demonstration against the Basic Law Article 23 in 2003.
