The couple's daughter blames herself for persuading them to surrender to the Immigration Department. 'I was only thinking of myself,' Tang On-yi said. 'I just didn't want to carry on living the way we were, hiding from the authorities. So I encouraged them to surrender themselves. Now I regret my decision so very much.' Since her parents were jailed in June, On-yi, 19, has had to care for her eight-year-old twin brothers. She is now studying Form Three level at an evening school and hopes to go to university. 'But I will not be going to university if my parents are repatriated to the mainland after their release,' she said. On-yi was taught by her parents at home before obtaining permanent residency last year. She said the judge did not understand the hardships the family faced. 'I think the judgment is laughable. The judge seems to think we have spent our past 20 years very happily. He did not give a thought as to how we came to be in such a situation,' she said. 'My parents did everything they did for the good of me and my brothers.' Her brothers still did not know their parents were in jail and had been withdrawn and quiet since their mother and father went away, she said.
