Perhaps you should try some spelling variations:
chong nam » phuong nam, chong wan, chong yah
yan clan » das clan, yan guan, yan yuan
clan run » can run
dan yang » daun yang, wang yang, yang yang
tan yang » tan ying, tan yong, tao yang
wan yan » wang yan, nan yan, wai yan
chong » clong
hong » long

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: wan yan clan run ((dan yang) OR (tan yang)) lin ((chong nam) OR (hong tan)) ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "wan yan clan run ((dan yang) OR (tan yang)) lin ((chong nam) or (hong tan)) ;~".
• Adding a wildcard symbol may retrieve word variants: wan yan clan run ((dan yang) OR (tan yang)) lin ((chong nam) or (hong tan)) ;*.
