我用铅笔画出了彩虹我用橡皮擦去了乌云
[wŏ yòng qiān bĭ huà chū le căi hóng wŏ yòng xiàng pí cā qù le wū yún]
'I drew the rainbow with pencils and erased the dark clouds with an eraser' represents a positive mindset towards life, emphasizing on transforming difficulties (symbolized as dark clouds) into beauty (rainbow) through effort.
