Perhaps you should try some spelling variations:
wang yang » wang yan, wang liang, wang yanling
dang hari » dang hai
ran ying » fan ying, tan ying, jin ying
yang wie » yang jie, lang wien, yang di
wie rene » wilke rene, wie deine, wie eine
ying jin » yang jin, jing ji, yang jie
thai » than

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

• Performing a fuzzy search may retrieve terms with similar spellings: ((wang yang) or (ran ying)) yang wie rene ying jin ((dang hari) or (dang (hai OR thai))) ;~.
• If you are trying to use Boolean operators, they must be ALL CAPS: ((wang yang) OR (ran ying)) yang wie rene ying jin ((dang hari) OR (dang (hai OR thai))) ;*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((wang yang) or (ran ying)) yang wie rene ying jin ((dang hari) or (dang (hai OR thai))) ;*".
