I'm so excited that she doesn't even know that she's actually revealing her truth because this means she took a sample of both of their hair and it shows that they are not sisters but Grandpa already has a DNA test between his eldest granddaughter and his son to prove that they are related
the test will show that zhenzhen and ye qiao are not blood relatives. it does not necessarily mean that ye qiao is not her father's biological daughter. perhaps zhenzhen is not shengxun's biological daughter? why is qin lan so anxious?
