Perhaps you should try some spelling variations:
costs patients » cost patient, courts patient, doctors patients
patients risk » patient risk, patients links, patients si
yang jun » yang jui, pang jun, yang jin
how slow » how low, how slower, grow slow
yang up » yang jui, tying up, hang ups
yang xi » yang di, yang yi, yang jui
wang » wing, 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 yanling ((((yang up) OR (yang jun))) OR (yang xi)) costs patients risk how slow ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "wang yanling ((((yang up) OR (yang jun))) or (yang xi)) costs patients risk how slow ;~".
• Adding a wildcard symbol may retrieve word variants: wang yanling ((((yang up) OR (yang jun))) or (yang xi)) costs patients risk how slow ;*.
