轻装上阵

Literally means:

go into battle with a light pack

Actually means:

get down to work without any worries

It originally means that an army goes into battle with light weapons for the convenience of mobility. Now it is used to mean going forward with one's without any worries.

原指为了行动方便,部队只带轻型武器上战场。现比喻抛掉精神负担,带着轻松的心情投入工作或学习。
