Why is "Taiwanese nationalism" trending?

Wikipedia Overview

Taiwanese nationalism is a nationalist political movement that promotes the cultural identity and unity of Taiwanese people as a nation. In recent decades, it consists of cultural or political movements that seek to resolve the current political and social division on the issues of Taiwan's national identity, political status, and political dispute with China. It is closely linked to the Taiwan independence movement but distinguished from it in that the independence movement seeks to eventually establish an independent "Republic of Taiwan" in place of or out of the existing Republic of China and obtain United Nations and international recognition as a sovereign state, while nationalists seek only to establish or reinforce an independent Taiwanese identity that distinguishes Taiwanese people apart from the Chinese nation, without necessarily advocating changing the official name of the country.
