Perhaps you should try some spelling variations:
wang liang » wang yang
wang yong » wang yang, wang hyoung, wang yan
lee sang » lee ann
tin hong » tan hong, kia hong, thi hong
min hong » amin hong, min hyoung, min jeong
yuan li » yuan lin, guan li, yuan zi
yan li » yang li, gan li, tan li

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 liang) OR (wang yong)) ((yan li) OR (yuan li)) lee sang ((min hong) OR (tin hong)) shu ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((wang liang) or (wang yong)) ((yan li) OR (yuan li)) lee sang ((min hong) or (tin hong)) shu ;~".
• Adding a wildcard symbol may retrieve word variants: ((wang liang) or (wang yong)) ((yan li) OR (yuan li)) lee sang ((min hong) or (tin hong)) shu ;*.
