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 _
waking up » making up, taking up, shaking up
yang jin » yang jie, yang jun, ying jin
1 laying » _ playing, 3 playing, 4 playing
shui » shi, hui, shu

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

• The words AND, OR and NOT may confuse the search; try adding quotes: "wan yanling ((((waking up) OR (yang jin))) OR (yang di)) cleft patients 1 laying shui ;~".
• Adding a wildcard symbol may retrieve word variants: wan yanling ((((waking up) OR (yang jin))) OR (yang di)) cleft patients 1 laying shui ;*.
