染指红颜笑冰似绕指柔
[răn zhĭ hóng yán xiào bīng sì răo zhĭ róu]
This refers to touching ('dyeing a finger') on beautiful young ladies ('红颜' referring to fair and lovely women), smiling at icy conditions and comparing it all to something very soft. The meaning conveys tenderness despite hardships, with an emphasis on charm during cold times, likely inspired by historical romance stories or poetry.
