Perhaps you should try some spelling variations:
wang yong » wang yang, wang hyoung, wang yan
yang hua » wang hua, ying hua, yang jui
yang hui » yang jui, wang hui, yang muxi
tan yang » dan yang, tan ying, tao yang
tan yong » tan hong, tan kong, tan ying
song shu » cong shu, song shin, tong shui
li song » li cong, li rong, kim song

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 yong ((yang hua) OR (yang hui)) ((tan yang) OR (tan yong)) li song shu ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "wang yong ((yang hua) or (yang hui)) ((tan yang) OR (tan yong)) li song shu ;~".
• Adding a wildcard symbol may retrieve word variants: wang yong ((yang hua) or (yang hui)) ((tan yang) OR (tan yong)) li song shu ;*.
