Perhaps you should try some spelling variations:
liang han » liang dan, kang han, liang sun
liang tan » liang dan, liang sun, wing tan
wang jing » wang ning, wang liang, wang yang
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) OR (liang tan)) rui dr wang jing ((((hong ma) OR (kong yam))) OR (zhong tai)) ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "wang ((liang han) OR (liang tan)) rui dr wang jing ((((hong ma) or (kong yam))) or (zhong tai)) ;~".
• Adding a wildcard symbol may retrieve word variants: wang ((liang han) OR (liang tan)) rui dr wang jing ((((hong ma) or (kong yam))) or (zhong tai)) ;*.
