Perhaps you should try some spelling variations:
chen wang » chen rong, chen ping
chen yang » chen rong
hua irene » hua ren
yang hua » wang hua, yang hui, ying hua
ying jin » yang jin, jing ji, yang jie
wong sau » wong sam, wong siu, wong shiu
yang xi » yang yi, yang jui

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

• Performing a fuzzy search may retrieve terms with similar spellings: ((chen wang) OR (chen yang)) yang hua irene ((ying jin) or (((yang xi) or (yang di)))) wong sau ;~.
• If you are trying to use Boolean operators, they must be ALL CAPS: ((chen wang) OR (chen yang)) yang hua irene ((ying jin) OR (((yang xi) OR (yang di)))) wong sau ;*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((chen wang) OR (chen yang)) yang hua irene ((ying jin) or (((yang xi) or (yang di)))) wong sau ;*".
