乌云一层一层的遮住了光坚强一层一层卸掉了伪装
[wū yún yī céng yī céng de zhē zhù le guāng jiān qiáng yī céng yī céng xiè diào le wĕi zhuāng]
A metaphorical expression depicting a state where sadness accumulates like layers of dark clouds blocking the light; however, it also represents peeling off layer by layer of the defensive persona to face oneself genuinely, revealing inner pain and sorrow while displaying resilience despite difficulties encountered over time.
