Perhaps you should try some spelling variations:
und thanh » und tanz
kong john » wong john, longo john, wrong john
lang und » klang und, langs und, gang und
thanh vu » thanh van, thanh _
vu irene » _ irene
yang jui » yang judy, yang xi, yang yi
wong siu » wong shiu, kong siu, 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: lang und thanh vu irene ((((kong john) or (king john))) or (((yang jui) OR (yang di)))) wong siu ;~.
• If you are trying to use Boolean operators, they must be ALL CAPS: lang und thanh vu irene ((((kong john) OR (king john))) OR (((yang jui) OR (yang di)))) wong siu ;.
• The words AND, OR and NOT may confuse the search; try adding quotes: "lang und thanh vu irene ((((kong john) or (king john))) or (((yang jui) OR (yang di)))) wong siu ;".
• Adding a wildcard symbol may retrieve word variants: lang und thanh vu irene ((((kong john) or (king john))) or (((yang jui) OR (yang di)))) wong siu ;*.
