我做过痞子爱过美人我留过长发爱过烂人
[wŏ zuò guò pĭ zi ài guò mĕi rén wŏ liú guò zhăng fā ài guò làn rén]
This is an autobiographical expression reflecting the different stages or aspects of one's life, acknowledging both the less admirable ('punk' or mischievous) past self and the experiences with different types of relationships, including loving people regarded as beautiful and also those considered 'unworthy'.
