The Migrant Enquiry Centre is crammed with distressed families. A mother gestures angrily and shouts, another weeps at a deportation order which will force her to leave a sick husband. Police rush into an apartment and haul out a woman and her 8 year old child. Faced with a 20 year backlog of migrant applications, the Hong Kong authorities are giving deportations a high profile, trying to deter illegal immigrants. Mrs Kwok has already been deported five times. Each time she begs or bribes officials in China to return to her husband. Wheezing with lung cancer, he can't cope with their three children alone. At the Chinese border old ladies with suitcases run through the customs hall towards Hong Kong. Even if they qualify for Hong Kong residency only 150 are allowed a day. In her one room apartment, Mrs Chang proudly displays her permanent residency. It means her children can go to school. From a tour bus wealthy Chinese glimpse Hong Kong , touring China's new jewel, one most Chinese have heard of but few will ever see.
