刻骨銘心的愛痛徹骨髓的怨
[kè gú míng xīn de ài tòng chè gú suĭ de yuàn]
'Heartfelt love and penetrating hatred' embodies two extremes of human emotion: deep love that touches the heart and hatred rooted deep in bone, expressing an extremely strong and complex emotional experience that may be unforgettable throughout one's life.
