Perhaps you should try some spelling variations:
yang guang » yang yang, yan guan, yang liang
di terence » di erence, liu terence, _ terence
wang yang » wang yan, wang liang, wang yanling
wong yue » wang yue
di rene » di rete, dr rene, ii rene
i rene » i reine, ii rene, _ rene
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 ((((di rene) OR (i rene))) OR (di terence)) gan li ((hong yu) OR (wong yue)) ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "wang yang guang ((((di rene) or (i rene))) or (di terence)) gan li ((hong yu) OR (wong yue)) ;~".
• Adding a wildcard symbol may retrieve word variants: wang yang guang ((((di rene) or (i rene))) or (di terence)) gan li ((hong yu) OR (wong yue)) ;*.
