Perhaps you should try some spelling variations:
yang yang » wang yang, wang yan
hua rene » hua ren, juan rene
yang xin » yang jin, yang lin, zhang xin
eng seng » hang seng, peng yeng, song seng
yu wang » yue wang, yu fang, yu yang
yu gang » xu gang, yi gang, yu fang
yang xi » yang di, yang yi, yang jui

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 ((((yu wang) OR (yu gang))) OR (yang yang)) hua rene ((yang xin) OR (yang xi)) eng seng ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "yang ((((yu wang) OR (yu gang))) or (yang yang)) hua rene ((yang xin) or (yang xi)) eng seng ;~".
• Adding a wildcard symbol may retrieve word variants: yang ((((yu wang) OR (yu gang))) or (yang yang)) hua rene ((yang xin) or (yang xi)) eng seng ;*.
