Perhaps you should try some spelling variations:
yuan ming » yuan ting, kian ming, tuan minh
wang dan » wang yan, wang ban, wang yidan
dan yang » daun yang, tan yang, wang yang
yang lin » yang jin, wang lin, yang li
anh ming » anh minh, wan ming
lin lin » lin ling, li lin, lia lin
long do » long d, long du, longer do

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: wang dan yang lin lin ((anh ming) OR (yuan ming)) ((kong do) OR (long do)) ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "wang dan yang lin lin ((anh ming) or (yuan ming)) ((kong do) OR (long do)) ;~".
• Adding a wildcard symbol may retrieve word variants: wang dan yang lin lin ((anh ming) or (yuan ming)) ((kong do) OR (long do)) ;*.
