Perhaps you should try some spelling variations:
yang wang » yang guang, yang liang, wang yang
yang yang » wang yang, wang yan
huei ying » hui ying, hoi ying
yan wang » yuan wang, qian wang, yan liang
yuan kuo » yan kun, yuan hui, yuan kai
kuo huei » huo hui
ii long » i long, ii losung

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: ((((yang wang) OR (yan wang))) OR (yang yang)) yuan kuo huei ying ((ii long) OR (die losung)) du ;~.
• Adding a wildcard symbol may retrieve word variants: ((((yang wang) or (yan wang))) or (yang yang)) yuan kuo huei ying ((ii long) or (die losung)) du ;*.
