天黑别怕手给我有我在
[tiān hēi bié pà shŏu jĭ wŏ yŏu wŏ zài]
'Don't be scared when it gets dark, just take my hand. I am here' This expresses a protective, reassuring sentiment - being available as a source of strength, comfort, and courage for another in times of uncertainty or fear, metaphorically represented by darkness.
