Perhaps you should try some spelling variations:
yang hong » wang hong, yang hongli, quang hong
hua irene » hua ren
yan ying » fan ying, ran ying, yan yuxing
tan ying » fan ying, ran ying, tan yang
wong sau » wong sam, wong siu, wong shiu
wang » wing, wan, lang
kong » long, pong, ong

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