J and Jacky are good friends who attend the same school. J is from a single-parent family, and will be taken care by Jacky’s family whenever his mother has to return to Mainland to renew her visa; such kind of story is not an isolated case. These families have been uprooted for a “better future” in Hong Kong, but is this “future” that the children really long to have? A Chinese saying: “How does one understand the joy of fish, if one is not a fish?” Will the adults really understand what the children want?
