Perhaps you should try some spelling variations:
china zhang » china chang, cheng zhang, chin chang
zhang soon » chang soon
yang yang » wang yang, wang yan
tan yong » tan hong, tan kong, tan yang
wang yue » wang hua, wang yan, wang he
wong yue » hong yu
3 china » 2 china, 4 china, 3 china's
yang xi » yang di, yang yi, yang jui

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: lang ((tan yong) OR (yang yang)) 3 china zhang soon ((((wang yue) OR (wong yue))) OR (yang xi)) ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "lang ((tan yong) or (yang yang)) 3 china zhang soon ((((wang yue) OR (wong yue))) or (yang xi)) ;~".
• Adding a wildcard symbol may retrieve word variants: lang ((tan yong) or (yang yang)) 3 china zhang soon ((((wang yue) OR (wong yue))) or (yang xi)) ;*.
