我每天牵着朝阳的手
在酸甜苦辣中奔走
咽不完的委屈
尝不完的哀愁
心酸塞满了我的胸口
我每天拉着夕阳的袖
在聚散离合中停留
数不完的孤独
赶不走的难受
孤独潜伏在我的伤口
我在人间晃晃悠悠
多少时候不知该往哪走
心里的苦没有人看透
眼里的泪也不敢流
我在人间停停走走
不知不觉渡过多少春秋
脸上的笑骗不过眉头
身上的伤何时方休
我每天牵着朝阳的手
在酸甜苦辣中奔走
咽不完的委屈
尝不完的哀愁
心酸塞满了我的胸口
我每天拉着夕阳的袖
在聚散离合中停留
数不完的孤独
赶不走的难受
苦痛潜伏在我的伤口
我在人间晃晃悠悠
多少时候不知该往哪走
心里的苦没有人看透
眼里的泪也不敢流
我在人间停停走走
不知不觉渡过多少春秋
脸上的笑骗不过眉头
身上的伤何时方休
我在人间晃晃悠悠
多少时候不知该往哪走
心里的苦没有人看透
眼里的泪也不敢流
我在人间停停走走
不知不觉渡过多少春秋
脸上的笑骗不过眉头
