Mainlanders desperate to join their families in Hong Kong say they are being denied the chance to make the move because of official inflexibility in filling quotas. Under the one-way permit system, there are 150 places available a day for mainland people under various categories to settle in the city. But last year, on average only 104 mainland migrants a day came to Hong Kong. The reason for this, according to the government, is that out of 60 places reserved for children under 18, only 28 were taken. This has led to calls for the government to cut the waiting list by filling the quota for children with people from other categories. 'I have the feeling the government only wants people to come to Hong Kong if they have money,' said Liu Shaojin, a mother of two who has been waiting for approval to settle in the city since 1996, when she married a Hong Kong man, Tang Kei-on. Speaking from a cramped flat in Cheung Sha Wan that the family has borrowed from a friend, Ms Liu said she was desperate to settle in Hong Kong so she could find a job and help with the family's finances. Her son, Tang Jun-yin, 8, who was born on the mainland, would also be able to resume his studies if allowed to settle here, she said. Jun-yin has been waiting for approval to settle since he was born and is visiting Hong Kong on a three-month visa with his mother. The government said the unused children quota should not be reallocated to other categories because the increase in the one-way permit quota - made before the handover - was intended to cater to children of Hong Kong residents. But the Society for Community Organisation, which has been helping the Tang family, felt the government should take a different approach. 'There are other people facing the same problem as the Tangs, and the government would be wrong to think there are fewer people waiting to come to Hong Kong because not all the quotas were used,' said Sze Lai-shan, a community organiser with the society. In a move that could cut short the waiting time for mainland residents to come to Hong Kong, the government has urged the mainland authorities to consider allowing more adult children to come to the city to take care of their Hong Kong parents. But the mainland authorities have yet to give a concrete response to this suggestion.
