Perhaps you should try some spelling variations:
yang guang » yan guan, yang liang
yang yang » wang yang, wang yan
dii rene » iii rene, dr rene, i rene
ii rene » iii rene, i rene, wie rene
li song » li cong, li rong, kim song
song yu » song yun, hong yu, rong yu
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) OR (yang yang)) ((((dii rene) OR (ii rene))) OR (di erence)) gan li song yu ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "wang ((yang guang) OR (yang yang)) ((((dii rene) or (ii rene))) or (di erence)) gan li song yu ;~".
• Adding a wildcard symbol may retrieve word variants: wang ((yang guang) OR (yang yang)) ((((dii rene) or (ii rene))) or (di erence)) gan li song yu ;*.
