密密麻麻深深浅浅的刀割
[mì mì má má shēn shēn qiăn qiăn de dāo gē]
It symbolizes numerous cuts or injuries which cause various degrees of hurt—both light ones on surface and severe ones underneath skin. Such wounds stand for accumulated emotional traumas or distress one suffered deeply within oneself rather than showing them outside clearly. They suggest an internal struggle and pain not obvious to others.
