Perhaps you should try some spelling variations:
yang john » young john, yang jin, kong john
yan yang » yang yang, yao yang, dan yang
yu cheng » yu chen, _ cheng
yang jun » yang jui, pang jun, yang jin
wong sau » wong sam, wong siu, wong shiu
wan yan » wang yan, nan yan, wai yan
yang yu » yang yue, yang yun, yang yi

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

• Performing a fuzzy search may retrieve terms with similar spellings: wan yan yang yu cheng ((((yang john) OR (yang jun))) or (king john)) wong sau ;~.
• If you are trying to use Boolean operators, they must be ALL CAPS: wan yan yang yu cheng ((((yang john) OR (yang jun))) OR (king john)) wong sau ;.
• The words AND, OR and NOT may confuse the search; try adding quotes: "wan yan yang yu cheng ((((yang john) OR (yang jun))) or (king john)) wong sau ;".
• Adding a wildcard symbol may retrieve word variants: wan yan yang yu cheng ((((yang john) OR (yang jun))) or (king john)) wong sau ;*.
