Perhaps you should try some spelling variations:
yong yang » ying yang, kyoung yang, yong phang
yang yang » wang yang, wang yan
dong yang » dong hoang, wang yang, dan yang
chan ming » kian ming, chan eng, chan fong
wong siu » wong shiu, kong siu, wong sau
von sach » von fach, von sprach, von sa
li chan » li chen, lily chan, li zhang
di li » li li

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

• Performing a fuzzy search may retrieve terms with similar spellings: wang ((((yong yang) OR (yang yang))) or (dong yang)) di li chan ming ((wong siu) or (von sach)) ;~.
• If you are trying to use Boolean operators, they must be ALL CAPS: wang ((((yong yang) OR (yang yang))) OR (dong yang)) di li chan ming ((wong siu) OR (von sach)) ;*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "wang ((((yong yang) OR (yang yang))) or (dong yang)) di li chan ming ((wong siu) or (von sach)) ;*".
