累了就微笑困了就睡觉
[lĕi le jiù wēi xiào kùn le jiù shuì jué]
Smile When Tired and Sleep When Feeling Lazy. This reflects an attitude of going with the flow. If feeling fatigued, then force yourself to muster up a happy face. While tired from hard work, it’s also alright to just let the body rest and get proper sleep.
