Perhaps you should try some spelling variations:
yang guang » yang yang, yan guan, yang liang
wang yang » wang yan, wang liang, wang yanling
dii rene » iii rene, dr rene, i rene
ii rene » iii rene, i rene, wie rene
song yu » song yun, hong yu, sang yu
rong yu » hong yu, rong su, wong yue
erence » terence, terrence
gan » gain, gang, ganz

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 guang ((((dii rene) OR (ii rene))) OR (di erence)) gan li ((song yu) OR (rong yu)) ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "wang yang guang ((((dii rene) or (ii rene))) or (di erence)) gan li ((song yu) OR (rong yu)) ;~".
• Adding a wildcard symbol may retrieve word variants: wang yang guang ((((dii rene) or (ii rene))) or (di erence)) gan li ((song yu) OR (rong yu)) ;*.
