Perhaps you should try some spelling variations:
und thanh » und tanz
kind john » king john, hinde john, und john
lang und » klang und, langs und, gang und
thanh vu » thanh van, thanh _
vu irene » _ irene
yang jun » yang jui, pang jun, yang jin
wong siu » wong shiu, kong siu, wong sau

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 und thanh vu irene ((kind john) OR (yang jun)) wong siu ;~.
• Adding a wildcard symbol may retrieve word variants: lang und thanh vu irene ((kind john) or (yang jun)) wong siu ;*.
