Perhaps you should try some spelling variations:
yang yang » wang yan
wang yang » wang yan, wang liang, wang yanling
tan chia » tuan china, than china, can china
tan jong » tan hong, tan kong, tan yong
jong min » gong min, song min, song ming
min dang » yimin dang, mein dank, bin dann
hai » hadi, haji, hari

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: ((yang yang) OR (wang yang)) ((tan chia) OR (wang hua)) tan jong min dang hai ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((yang yang) OR (wang yang)) ((tan chia) or (wang hua)) tan jong min dang hai ;~".
• Adding a wildcard symbol may retrieve word variants: ((yang yang) OR (wang yang)) ((tan chia) or (wang hua)) tan jong min dang hai ;*.
