Perhaps you should try some spelling variations:
yang guang » yang yang, yan guan, yang liang
yang john » young john, king john, yang jin
ren yang » ren yan, chen yang, dan yang
wong sam » wong sau, wong lai, kong sar
song pae » song ze
hua ren » hua chen
song so » song von
nan ya » nan yan, nana yaa

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: lang ((yang guang) OR (nan ya)) hua ren yang john ((((song so) OR (wong sam))) OR (song pae)) ;~.
• Adding a wildcard symbol may retrieve word variants: lang ((yang guang) or (nan ya)) hua ren yang john ((((song so) or (wong sam))) or (song pae)) ;*.
