Perhaps you should try some spelling variations:
ying yang » yang yang, yin yang, ying chang
kong saur » kong sar, kong siu, wong sau
kong your » kong young, knowing your
yong yan » yang yang, dong yang, yong yoon
hua rent » hua ren
yang jin » yang jie, yang jun, ying jin
yan jiu » yang jie, pang jiu

You may be able to get more results by adjusting your search query.

• Performing a fuzzy search may retrieve terms with similar spellings: wang ((yong yan) or (ying yang)) hua rent ((yan jiu) OR (yang jin)) ((kong saur) or (kong your)) ;~.
• If you are trying to use Boolean operators, they must be ALL CAPS: wang ((yong yan) OR (ying yang)) hua rent ((yan jiu) OR (yang jin)) ((kong saur) OR (kong your)) ;.
• The words AND, OR and NOT may confuse the search; try adding quotes: "wang ((yong yan) or (ying yang)) hua rent ((yan jiu) OR (yang jin)) ((kong saur) or (kong your)) ;".
• Adding a wildcard symbol may retrieve word variants: wang ((yong yan) or (ying yang)) hua rent ((yan jiu) OR (yang jin)) ((kong saur) or (kong your)) ;*.
