Korean names written in hanja keep their Chinese characters but are read in Mandarin:
崔 Cuī (Korean Choi 최),
太雄 Tàixióng (Korean Tae-woong 태웅, "great hero"). The Choi/Cui surname covers about 5% of South Korea's population. In Chinese-language Korean drama subtitles, characters are routinely referred to by their hanja names.
