The last line of defense Some argue that when persons can't express their own will, family members should be given the right to decide for them, based on the Chinese conception that "no one knows the parent like the child, no one knows the child like the parent." In this view family morality serves as the last line of defense and support.
也有人認為在一個人的自由意志無法執行、表達時，至親至愛的家屬應有代為決定的權利。因為中國人相信「知子莫若母」、「知母莫若子」，認為天倫、親情是最後的防線與支撐。
