Perhaps you should try some spelling variations:
yang yang » wang yang, wang yan
sing kong » king kong, hong kong
lan sing » plan using, land using, man sings
kong sun » cong sun, kong sar, kong lyn
yang li » yang lin, yang di, yang yi
yang xi » yang di, yang yi, yang jui
lai lan » li lan, mai land

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

• Performing a fuzzy search may retrieve terms with similar spellings: wan daud ((((yang li) or (yang yang))) or (yang xi)) lai lan sing kong sun ;~.
• If you are trying to use Boolean operators, they must be ALL CAPS: wan daud ((((yang li) OR (yang yang))) OR (yang xi)) lai lan sing kong sun ;*.
