The father of four-year-old right-of-abode claimant Chan Wai-wa said his boy would become homeless if the Government won its appeal to bar adopted mainland children from Hong Kong. Tsang Heung-choi, 48, said he was extremely worried about losing his adopted son and felt helpless as the fate of Wai-wa was undetermined. Mr Tsang married in Guangzhou more than 10 years ago but the couple were unable to have children. They turned for help to Mr Tsang's aunt, who has five children all living in Chao Zhou (Chiu Chow). The aunt gave Wai-wa to the couple when the child was two months. The boy was smuggled into Hong Kong on April 7, 1997 and later adopted on the mainland. 'We love Wai-wa very much and we treat him as if he was our natural son,' Mr Tsang said. Asked what would happen if the Government succeeded, he said: 'My boy would become homeless because there would be no one to take care of him in his home town and at the same time, he could not stay in Hong Kong. 'I and my wife feel very lonely and hope very much our son can be with us.' The boy had brought joy to their lives, he said. Mr Tsang said his wife, Wong Sek-lan, 44, who came to Hong Kong in October 1994, cried whenever she thought of the court case. 'She is very unhappy and so afraid that one day our son will be taken away from us.' Another applicant's father, Tam Ching-luk, 70, said he was very angry about the Government's appeal because it was intended to split up families. He adopted Tam Nga-yin, now 13, on the mainland when she was only three months old. The girl entered the SAR on a two-way permit in February 1997. 'I would not send my daughter back to China even if the ruling goes against us,' he said.
