10.1 among » 1.8 among
1.5 among » 1.8 among, 2.15 among, 19 among
yan yang » yang yang, yao yang, dan yang
yang fan » zhang fan, yang dean, yang yang
fan de » van de, aan de, jan de
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) yan yang fan de patients ((10.1 among) OR (1.5 among)) masters ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "(wang or wing) yan yang fan de patients ((10.1 among) OR (1.5 among)) masters ;~".
• Adding a wildcard symbol may retrieve word variants: (wang or wing) yan yang fan de patients ((10.1 among) OR (1.5 among)) masters ;*.
