Perhaps you should try some spelling variations:
yang yang » wang yang, wang yan
juan rene » juan meng
juan rana » juan danza, juan lara
tan yang » dan yang, tan ying, tan yong
kang kim » kanaga kim, tan kim, yong kim
song sau » wong sau, kong sar, song so
song pae » song ze

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: tan yang yang ((juan rene) OR (juan rana)) kang kim ((song sau) OR (song pae)) ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "tan yang yang ((juan rene) OR (juan rana)) kang kim ((song sau) or (song pae)) ;~".
• Adding a wildcard symbol may retrieve word variants: tan yang yang ((juan rene) OR (juan rana)) kang kim ((song sau) or (song pae)) ;*.
