Perhaps you should try some spelling variations:
yang yang » wang yang, wang yan
yang wang » yan wang, yang guang, yang liang
peng send » peng sen, eng seng
peng yeng » peng sen, eng seng
hua rene » hua ren, juan rene
yu fang » yu gang, yu wang, yin fang
yu yang » du yang, yi yang, yu gang

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

• Performing a fuzzy search may retrieve terms with similar spellings: yang ((((yu fang) OR (yu yang))) or (yang yang)) hua rene yang wang ((peng send) or (peng yeng)) ;~.
• If you are trying to use Boolean operators, they must be ALL CAPS: yang ((((yu fang) OR (yu yang))) OR (yang yang)) hua rene yang wang ((peng send) OR (peng yeng)) ;*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "yang ((((yu fang) OR (yu yang))) or (yang yang)) hua rene yang wang ((peng send) or (peng yeng)) ;*".
