I'm so sick of this"West Taiwan" crap. It plays into the PRC narrative that China and Taiwan are inseparable. Most Taiwanese just want to live their lives without needing to worry about China invading. The official ROC territorial claims remain in part due to the 2005 Anti-Secession law of the PRC. The law provides a legal mandate to invade if Taiwan were to declare formal independence. In general the only people in Taiwan who want to govern China are older nationalists.
