Is Nikun's mother Chinese American or Chinese Thai?

Nie Kun's family should all be Mattel's dual nationality. His grandmother is from Hainan and his grandfather is from Taiwan Province Province. When I married him, he said that his grandmother was from Hainan because he couldn't tell Korean from his grandmother. Later, Victoria Song corrected him. In an interview, he said that when his mother and sister are in Thailand and his father and brother are in the United States, his brother and sister will go to grandma's house in the United States to play. His parents also speak English (mother speaks English with mother Mia at my wedding, and father speaks English when he goes to Korea for his birthday). He was born in America.
