Perhaps you should try some spelling variations:
wang kang » wang liang, wang yan, wang yong
wang yang » wang yan, wang liang, wang yanling
hear gain » heat gain
zhong zhi » zhang zhi, hong ghi, zhong tai
can hear » can gear, can learn, can help
yang li » yang lin, yang di, tang li
yang yi » yang di, yang jui
yang xi » yang di, yang jui

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