答案:答:脸(lian)– Lian is part of decency, because it is assumed that a decent person's behaviour is up to a standard. When we do something face to face, our performance is assessed by others who observe us against certain criteria such as job description, duties, responsibilities, undertaking, assumed expertise, moral character, prior claims, or other public standards. Our lian is lost, in one way or another, lightly or seriously, if the assessment is negative.
