Perhaps you should try some spelling variations:
wang kang » wang yang, wang liang, wang yan
zhong zhi » zhang zhi, hong ghi, zhong tai
can hear » can learn, can help, can earn
can gear » can learn, can get, can earn
yang lin » yang jin, wang lin, yang li
yang jui » yang judy, yang di, yang yi
yang xi » yang di, yang yi

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 kang ((can hear) OR (can gear)) gain ((((yang lin) OR (yang jui))) OR (yang xi)) zhong zhi ;~.
• Adding a wildcard symbol may retrieve word variants: wang kang ((can hear) or (can gear)) gain ((((yang lin) or (yang jui))) or (yang xi)) zhong zhi ;*.
