Perhaps you should try some spelling variations:
yang guang » yang yang, yan guan, yang liang
quan guan » gan guan, quan guo, yan guan
yan shin » yan zhi, yun shik
dong sam » dong sin, kong sar, dong cao
wong sam » wong sau, wong lai, kong sar
hua ren » hua chen
wang » wan, lang

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

• Performing a fuzzy search may retrieve terms with similar spellings: (wang or wing) ((yang guang) or (quan guan)) hua ren yan shin ((dong sam) OR (wong sam)) ;~.
• If you are trying to use Boolean operators, they must be ALL CAPS: (wang OR wing) ((yang guang) OR (quan guan)) hua ren yan shin ((dong sam) OR (wong sam)) ;*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "(wang or wing) ((yang guang) or (quan guan)) hua ren yan shin ((dong sam) OR (wong sam)) ;*".
