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
li song » li rong, kim song, jie song
li cong » li rong, jiu cong
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) OR (li cong)) 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) OR (li cong)) yu ;~".
• Adding a wildcard symbol may retrieve word variants: wang yang guang ((((dii rene) or (ii rene))) or (di erence)) gan ((li song) OR (li cong)) yu ;*.
