Perhaps you should try some spelling variations:
costs patients » cost patient, courts patient, doctors patients
patients risk » patient risk, patients links, patients si
yang jui » yang judy, yang di, yang yi
how slum » how slow, how sub, how sun
yang up » tying up, yang jun, hang ups
yang xi » yang di, yang yi
wang » wan, lang

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: (wang OR wing) yanling ((yang up) OR (((yang jui) OR (yang xi)))) costs patients risk how slum ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "(wang OR wing) yanling ((yang up) or (((yang jui) or (yang xi)))) costs patients risk how slum ;~".
• Adding a wildcard symbol may retrieve word variants: (wang OR wing) yanling ((yang up) or (((yang jui) or (yang xi)))) costs patients risk how slum ;*.
