从白天到黑夜
                         从春天到秋天
                         你在忙，我在忙
                         忙忙碌碌
                         一天又一天
                         一年又一年
                         白了两鬓
                         老了容颜
                         历经了沧桑
                         世态炎凉早已变换
                         可喜的是
                         热情还在
                         年轻的初心一直未曾停歇
                         年过半百
                         人生的下半场已开启
                         都说最美不过夕阳红
                         那一份余热
                         那一份关切
                         也一样精彩
                         就像一列幸福的高铁
                         从北到南
                         从南到北
                         快乐地飞驰向前
