Perhaps you should try some spelling variations:
wang liang » wang yang
liang han » liang dan, liang tan, kang han
wang yong » wang yang, wang hyoung, wang yan
zhong tai » hong tan, hong hai, zhong zhi
kong yam » kong sar
dr wang » dr wong, mr wang, der zwang
hong ma » hong a, hong tan, hong hai

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 han (rui OR ruiz) dr wang yong ((((hong ma) OR (kong yam))) OR (zhong tai)) ;~.
• Adding a wildcard symbol may retrieve word variants: wang liang han (rui or ruiz) dr wang yong ((((hong ma) or (kong yam))) or (zhong tai)) ;*.
