Who is Elva Hsiao’s father?

Xiao’s father: 20 years after Xiao Yao abandoned his wife and daughter, Xiao Yaxuan’s father suddenly appeared and boasted: “If I had not left them, I might not have the Xiao Yaxuan that I am now.” In the past 20 years, he has only seen Xiao Yaxuan. Elva once and later secretly watched her daughter perform in public, but she did not recognize her. Regarding this sudden exposure and appearance as a celebrity dad, he explained that it was "fate has arrived"! Elva (Xiao) was born in a single family and was raised by her grandmother and mother. Yesterday, her biological father Xiao Yao (50 years old), whom she had not seen for 20 years, was suddenly exposed. In an interview with "Times Weekly", he admitted that after giving birth to Elva, he desperately divorced his wife because he wanted to study in the United States. He later obtained a doctorate in public health from Texas State University in the United States, and also served as the head of the Taiwan region of an international law firm. Currently, he is hosting the program "Xiaoyao Health Hall" on Changqing Network in the police station. During an exclusive interview with "Times", he was worried that he would hurt his daughter. But he still does not regret his decision to leave his wife and daughter, and believes that he gave his wife and children "freedom". He used the metaphor that trees can grow more vigorously in the wild than indoors, and that if he had not left, he might have suppressed the development of his children. Xiao Yao believed that he was a strict and possessive person who was not suitable for a family, so he decided to leave his wife and children. Although he had a girlfriend over the years, he never remarried. Twenty years ago, he returned to Taiwan from the United States to visit Elva, who was still in the third grade of elementary school. He never saw her again. Later, he learned from relatives that his daughter had become a singer. He also saw her at the Grand Hyatt Hotel, but he turned around and avoided her. Xiao Yao said: "I have nothing but blessings for my ex-wife and Elva Hsiao. My ex-wife is a very standard Taiwanese woman. I admire her for bringing up her children. I never went to find her and asked my relatives not to disturb her. If my daughter is famous now, I just went to see her, that’s bull shit, I have nothing to do with her success.” If that’s the case, why do you show up now? He said that the news was revealed by relatives and friends, and said: "It was fate that told me. This is also a difficulty for Elva Hsiao." He believes that Elva has the ability to overcome the difficulties of her life experience
