Perhaps you should try some spelling variations:
wilke rene » wie rene
yoon kian » hoon hian
yan kian » yan liang, yan clan, yan kun
yan guan » gan guan, yan yuan, yang guang
yang jui » yang judy, yang di, yang xi
jui chen » yi chen
chen yue » chen yu, chen yun, chen yulu

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

• Performing a fuzzy search may retrieve terms with similar spellings: (wing or wan) ((((yan kian) OR (yoon kian))) or (yan guan)) wilke rene yang jui chen yue ;~.
• If you are trying to use Boolean operators, they must be ALL CAPS: (wing OR wan) ((((yan kian) OR (yoon kian))) OR (yan guan)) wilke rene yang jui chen yue ;*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "(wing or wan) ((((yan kian) OR (yoon kian))) or (yan guan)) wilke rene yang jui chen yue ;*".
