Perhaps you should try some spelling variations:
cleft patients » select patients, les patients, benefit patients
cost patients » cost patient, care patients, des patients
among shui » among sri, tong shui
yang jun » yang jui, pang jun, yang jin
si among » ngi among, sex among, 19 among
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 di) OR (yang jun)) ((cost patients) OR (cleft patients)) si among shui ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "wang yanling ((yang di) or (yang jun)) ((cost patients) OR (cleft patients)) si among shui ;~".
• Adding a wildcard symbol may retrieve word variants: wang yanling ((yang di) or (yang jun)) ((cost patients) OR (cleft patients)) si among shui ;*.
