On the night of February 5, a netizen discover that Hanni's family still supports the Republic of Vietnam (South Vietnam) - the old government that was merged to North Vietnam to form the Socialist Republic of Vietnam (recent Vietnam).
It's a common belief in Vietnam that those who support the Republic of Vietnam are anti-communism, reactionary toward current government.
This causes an angry wave in Vietnam, and some Vietnamese are calling for a boycott wave to stop supporting this female idol. However, some Vietnamese fans still claim that her family's political life is irrelevant to her, and they says that they still support her anyway.
The political scandal of Hanni (NewJeans) are now the hot topic in Vietnam. News related to her are also deleted in many electronic newspaper supervised by government.
