The Mandarin / Teochew / Cantonese / Korean thing is, the words are the same but you say the words differently in different languages.
For example, Kim Jong Il is 金正日 (Jin Zheng Ri) in Chinese characters and Mandarin, which is gam1]正[jing3]日[yat6] in Cantonese, which is Kim Cheng Jit in Hokkien / Teochew.
(I’ve got a name like that too. Less dictatorial)
