在家靠父母，出门靠朋友

在家靠父母，出门靠朋友:

Literally means:

at home one relies on one's parents, and outside on one's friends

Actually means:

it is very important for one to have friends

靠, to rely on.

The whole phrase means one can rely on his parents at home, while once outside, he can only count on his friends for help.

The former half of the phrase serves to highlight the latter, stressing the importance of having friends when one is away from home.

It usually means one is willing to help his friends, or he holds the idea that friends should help each other.

靠，依靠。

在家靠父母，出门靠朋友，在家时可以依靠父母，离家出门在外则要依靠朋友的帮助。

前一部分是用来衬托后一部分的，借以突出离家在外依靠朋友的重要性。

常用来表示愿意帮助朋友，或朋友之间应该互相帮助。
