Perhaps you should try some spelling variations:
yan liang » yang liang, wang liang, you liang
yang yang » wang yang, wang yan
kong saur » kong sar, kong siu, wong sau
kong your » kong young, knowing your
li best » i best, als best, cio best
yan jiu » yang jie, yang jin, pang jiu
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 liang) OR (yang yang)) li best ((yan jiu) OR (yang di)) ((kong saur) OR (kong your)) ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "wang ((yan liang) or (yang yang)) li best ((yan jiu) or (yang di)) ((kong saur) OR (kong your)) ;~".
• Adding a wildcard symbol may retrieve word variants: wang ((yan liang) or (yang yang)) li best ((yan jiu) or (yang di)) ((kong saur) OR (kong your)) ;*.
