我知道我的心是黑的我知道我的心是红的
[wŏ zhī dào wŏ de xīn shì hēi de wŏ zhī dào wŏ de xīn shì hóng de]
Translates to 'I know my heart is black and I know my heart is red.' This expresses a dual nature within oneself: having a negative, possibly cynical side ('black heart'), as well as passion or innocence side ('red heart').
