Perhaps you should try some spelling variations:
wang yang » wang yan, wang liang, wang yanling
ran ying » fan ying, tan ying, jin ying
wie rene » wilke rene, wie deine, wie eine
yang jun » yang jui, pang jun, yang jin
ii rene » iii rene, i rene
jun how » junk how, gun how, sun how
how ai » how aid, how ae, how am

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 yang) OR (ran ying)) yang ((ii rene) OR (wie rene)) yang jun how ai ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((wang yang) or (ran ying)) yang ((ii rene) OR (wie rene)) yang jun how ai ;~".
• Adding a wildcard symbol may retrieve word variants: ((wang yang) or (ran ying)) yang ((ii rene) OR (wie rene)) yang jun how ai ;*.
