Did Tamia Liu children transfer to China hukou?

Both Tamia Liu's children were born in the United States. These stars spend a lot of money to choose to have children abroad, because according to American regulations, as long as a child is born in the United States, it is American nationality, so the United States has become the first choice for stars. In addition, these children can apply for permanent residency in the United States for their parents after they reach the age of 2 1, so it is easier to have children and immigrate than ordinary immigrants.
