Perhaps you should try some spelling variations:
cleft patients » select patients, les patients, benefit patients
wan yanling » wang yanling, wang yangming, wang danning
patients 1 » patients _
taking up » making up, waking up, shaking up
yang jie » yang jin, yang di, yang xi
yang jui » yang judy, yang di, yang xi
1 laying » _ playing, 3 playing, 4 playing
shui » shi, hui, shu

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: wan yanling ((((taking up) OR (yang jie))) OR (yang jui)) cleft patients 1 laying shui ;~.
• Adding a wildcard symbol may retrieve word variants: wan yanling ((((taking up) or (yang jie))) or (yang jui)) cleft patients 1 laying shui ;*.
