Perhaps you should try some spelling variations:
yuan kang » yuan chang, chan kang, yuan kai
yuan wang » yan wang, yuan chang, qian wang
yang yang » wang yang
weng wang » wen wang, weng fang, hong wang
yang yin » yang jin, yang lin, yang yun
yang yi » yang di, yang xi, yang jui
yan onn » yan cong
onn sau » wong sau

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

• Performing a fuzzy search may retrieve terms with similar spellings: ((((yuan kang) OR (yuan wang))) or (yang yang)) ((yang yi) or (yang yin)) weng wang yan onn sau ;~.
• If you are trying to use Boolean operators, they must be ALL CAPS: ((((yuan kang) OR (yuan wang))) OR (yang yang)) ((yang yi) OR (yang yin)) weng wang yan onn sau ;*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((((yuan kang) OR (yuan wang))) or (yang yang)) ((yang yi) or (yang yin)) weng wang yan onn sau ;*".
