初心还在心底待着不动
[chū xīn hái zài xīn dĭ dài zhe bù dòng]
'Chu Xin Hai Zai Xin Di Dai Zhuo Bu Dong' translates into 'The Original Heart Stays Still in the Heart'. It symbolizes the unshaken faithfulness or loyalty to one's original intent or feelings deep down despite everything else that has changed over time.
