                                                                                                    澳门
                                                                                    你可知“妈港”不是我的真名姓?……
                                                                                    我离开你的襁褓太久了，母亲!
                                                                                    但是他们掳去的是我的肉体，
                                                                                    你依然保管着我
                                                                                    内心的灵魂。
                                                                                    三百年来梦寐不忘的生母啊!
                                                                                    请叫儿的乳名，叫我一声澳门！
                                                                                    母亲!我要回来，母亲!
                                                                                                    香港
                                                                                    我好比凤阁阶前守夜的黄豹，
                                                                                    母亲呀，我身份虽微，地位险要。
                                                                                    如今狞恶的海狮扑在我身上，
                                                                                    啖着我的骨肉，嗳着我的脂膏；
                                                                                    母亲呀，我哭泣号啕，呼你不应。
                                                                                    母亲呀，快让我躲入你的怀抱!
                                                                                    母亲!我要回来，母亲!
                                                                                                     台湾
                                                                                    我们是东海捧出的珍珠一串，
                                                                                    琉球是我的群弟我就是台湾。
                                                                                    我胸中还氲氤着郑氏的英魂，
                                                                                    精忠的赤血点染了我的家传。
                                                                                    母亲，酷炎的夏日要晒死我了；
                                                                                    赐我个号令，我还能背城一战。
                                                                                    母亲!我要回来，母亲!
