Doctor , may I ask my mother ’ s condition ?   Well , you'd better sit down for this . It has been terminal lung cancer .   Oh my god . Please save her life .   We ’ ll try our best , but you'd better prepare for the worst .   I see , D . But I plead you to help her .   I have said that we will try our best . You can trust us . But you know her situation .   How long do you expect her to live ?   About half a year .
