Perhaps you should try some spelling variations:
yang guang » yang yang, yan guan, yang liang
wang yang » wang yan, wang liang, wang yanling
hong hong » hong kong, hong jong, hong ng
yan quang » doan quang, yan guan, yan liang
yang hua » wang hua, yang hui, ying hua
yang xi » yang di, yang yi, yang jui
hong yu » wong yue

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

• Performing a fuzzy search may retrieve terms with similar spellings: ((wang yang) or (hong hong)) ((yang hua) or (yang xi)) ren ((yan quang) OR (yang guang)) hong yu ;~.
• If you are trying to use Boolean operators, they must be ALL CAPS: ((wang yang) OR (hong hong)) ((yang hua) OR (yang xi)) ren ((yan quang) OR (yang guang)) hong yu ;.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((wang yang) or (hong hong)) ((yang hua) or (yang xi)) ren ((yan quang) OR (yang guang)) hong yu ;".
• Adding a wildcard symbol may retrieve word variants: ((wang yang) or (hong hong)) ((yang hua) or (yang xi)) ren ((yan quang) OR (yang guang)) hong yu ;*.
