Perhaps you should try some spelling variations:
failure patients » care patients
failure patient » failure treatment
wing yanling » wang yanling, wang yangming
risk cong » risk coping, risk among, risk along
yang jui » yang judy, yang di, yang xi
yang up » tying up, yang jun, hang ups

You may be able to get more results by adjusting your search query.

• If you are trying to use Boolean operators, they must be ALL CAPS: wing yanling ((yang up) OR (yang jui)) ((failure patient) OR (failure patients)) risk cong shu ;~.
• Adding a wildcard symbol may retrieve word variants: wing yanling ((yang up) or (yang jui)) ((failure patient) or (failure patients)) risk cong shu ;*.
