向阳笑往月哭
[xiàng yáng xiào wăng yuè kū]
'Towards the sun and laugh, but at night when facing the moon, weep.' It represents a person who is cheerful in front of others (like under the sunlight) and can keep smiling to move forward. However, in solitude or darkness (symbolized by moon here), he or she has the soft, vulnerable, and sorrowful side that needs a space to express.
