don’t worry about minor or unimportant things
不要为小事或不重要的事情担心 (bu yao wei xiao shi huo bu zhong yao de shi qing dan xin)
"It’s just a little mistake, don’t sweat the small stuff."
"这只是一个小错误，不要为小事担心。" (zhe zhi shi yi ge xiao cuo wu, bu yao wei xiao shi dan xin)
used when you meet someone after a long time
to manage to survive under pressure or financial difficulty
to face a difficult situation bravely
to get some sleep
old friends are precious and valuable
to praise yourself for doing something well
