Perhaps you should try some spelling variations:
wang liang » wang yang
wang yuhan » wang luhang, wang yan, wang yidan
gang hadi » dang hai
tan yang » dan yang, tan ying, tan yong
yan kun » yan guan, yan yuan
yang xi » yang di, yang yi, yang jui
xi gang » ii gang, i gang, li gang

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 ((wang yuhan) OR (yan kun)) tan yang xi gang hadi ;~.
• Adding a wildcard symbol may retrieve word variants: wang liang ((wang yuhan) or (yan kun)) tan yang xi gang hadi ;*.
