What is the "tattoo" on the hero's face in the classic love piano lesson in New Zealand?

The face of the hero Bain is called "tattooed face", which is a cultural form of indigenous Maori in New Zealand. Maori use tattooed faces to distinguish their identity, ethnicity and social class. The more tattoos on the face, the higher the status, while women only tattoo the lower part of their lips. Bain is English. Why did he get a tattoo? In fact, the director is telling the audience that he is a westerner assimilated by Maori culture. He can't read, but he knows Maori, so he can act as a translator and coordinator between whites and Maori. Because of Bain's recognition of Maori culture, he won the trust of the tribe and got a tattoo, because not every foreigner has this honor.

In addition, he is not a prisoner, Australia is a prisoner's exile, and New Zealand, as a British colony, has been regarded as a moral pure land from the beginning. In order to build New Zealand into a utopia in the eyes of westerners, the government even considers choosing excellent and diligent British as suitable immigrants as far as possible. The prison exile you mentioned is actually Australia, not far from New Zealand. /kloc-At the beginning of the 9th century, Australia was a famous dump in Britain. Prisoners, vagrants, infectious patients and lunatics are all transported to Australian prisons for detention. The original Australian Chief Executive was actually the warden of the prison. Materials are shipped from Britain, and Australia does not produce them locally, which has caused a heavy economic burden to Britain. It was not until the sheep industry flourished that Australia became a wealthy colony.
