Perhaps you should try some spelling variations:
among masters » among partners, among farmers, among actors
de patients » des patients, do patients, de pacientes
patients 1 » patients _
yan yang » yang yang, dan yang, yan wang
tan yang » dan yang, tan ying, tan yong
yao yang » yang yang
1 among » 19 among, 1.5 among, 1.8 among
fan de » van de, aan de, jan de
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 ((((yan yang) OR (tan yang))) OR (yao yang)) fan de patients 1 among masters ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "wang ((((yan yang) OR (tan yang))) or (yao yang)) fan de patients 1 among masters ;~".
• Adding a wildcard symbol may retrieve word variants: wang ((((yan yang) OR (tan yang))) or (yao yang)) fan de patients 1 among masters ;*.
