Perhaps you should try some spelling variations:
wang liang » wang yang
liang yang » liang ying, wang yang, yang yang
liu gang » liu gangs, liu yang, liu feng
min cong » minh cong, min hong, min jeong
yang yi » yang di, yang xi, yang jui
xi kang » jin kang, xi zhang
li gang » ii gang, i gang, li wang
li wing » li ying, li bing, li ning

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 yang yi ((((xi kang) OR (((li gang) OR (liu gang))))) OR (li wing)) min cong shu ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "wang liang yang yi ((((xi kang) or (((li gang) OR (liu gang))))) or (li wing)) min cong shu ;~".
• Adding a wildcard symbol may retrieve word variants: wang liang yang yi ((((xi kang) or (((li gang) OR (liu gang))))) or (li wing)) min cong shu ;*.
