Perhaps you should try some spelling variations:
yan guang » yang guang, yan guan, gan guan
guang hua » wang hua, gang hu, guang eu
hua irene » hua ren
ping john » king john, kong john, wong john
wong sam » wong sau, wong lai, von sam
wang » wing, wan, lang
sar » sara, star, saur

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

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