Perhaps you should try some spelling variations:
wang liang » wang yang
yang yun » yang jun, tang yun, yang yue
wong yue » wang yue, hong yu
tan yang » dan yang, tan ying, tan yong
yan yun » yan yuan, yan kun, yap yun
yang yi » yang di, yang xi, yang jui
yi dang » yi gang, yi yang, yi chang

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 ((((yan yun) OR (yang yun))) OR (wong yue)) tan yang yi dang (hai OR hadi) ;~.
• Adding a wildcard symbol may retrieve word variants: wang liang ((((yan yun) or (yang yun))) or (wong yue)) tan yang yi dang (hai or hadi) ;*.
