Perhaps you should try some spelling variations:
chia rene » chia wen, china ren
yan guan » gan guan, yang guang, yihan guan
yan yuan » fang yuan, nan yan, yan clan
yang jui » yang di, yang xi, yang yi
wong sau » wong sam, wong siu, wong shiu
yan tan » tan tan, yan clan, yan wang
wang » wing, wan, lang

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 tan) OR (((yan guan) OR (yan yuan)))) chia rene ((yang jui) OR (yang judy)) wong sau ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "wang ((yan tan) or (((yan guan) OR (yan yuan)))) chia rene ((yang jui) or (yang judy)) wong sau ;~".
• Adding a wildcard symbol may retrieve word variants: wang ((yan tan) or (((yan guan) OR (yan yuan)))) chia rene ((yang jui) or (yang judy)) wong sau ;*.
