As usual with Taiwan, it’s… complicated.
Residents of mainland China, which is now under the jurisdiction of the People’s Republic of China (PRC), were identified as nationals given the pre-1949 history of the Republic of China. In May 2023, Executive Yuan released a policy memorandum to clarify that: “The people of mainland China do not have ROC nationality, and hence are not ROC nationals.” (中國大陸人民不具中華民國國籍、非屬中華民國國民)[12] Legal scholars, on the other hand, argue that the matter is not resolved as executive branch explanations are not legally binding to courts. Hence, unless amended by the Legislative Yuan, both the Nationality Act and the Cross-Strait Act still include citizens of Mainland China (i.e., the PRC) as ROC nationals.
PS I have no idea who those two people on the poster are, they’re not the ones from the movie.
