Perhaps you should try some spelling variations:
yang guang » yang yang, yan guan, yang liang
wang yang » wang yan, wang liang, wang yanling
guang hua » wang hua, gang hu, guang eu
hua irene » hua ren
wong sam » wong lai, von sam, wong max
wong sau » wong siu, wong shiu, wong lai
king » wing, kind, ping
sar » sara, star, saur

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: wang yang guang hua irene king john ((((wong sam) OR (wong sau))) OR (kong sar)) ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "wang yang guang hua irene king john ((((wong sam) OR (wong sau))) or (kong sar)) ;~".
• Adding a wildcard symbol may retrieve word variants: wang yang guang hua irene king john ((((wong sam) OR (wong sau))) or (kong sar)) ;*.
