Perhaps you should try some spelling variations:
yang guang » yang yang, yan guan
yang liang » wang liang, yan liang, yang yang
yang john » young john, king john, yang jin
ren yang » ren yan, chen yang, dan yang
song sam » wong sam, kong sar, song so
song pae » song ze
hua ren » hua chen
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 (yang liang))) OR (nan ya)) hua ren yang john ((song sam) OR (song pae)) ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "lang ((((yang guang) OR (yang liang))) or (nan ya)) hua ren yang john ((song sam) or (song pae)) ;~".
• Adding a wildcard symbol may retrieve word variants: lang ((((yang guang) OR (yang liang))) or (nan ya)) hua ren yang john ((song sam) or (song pae)) ;*.
