Perhaps you should try some spelling variations:
binh thang » binh thanh, bin zhang, binh thuan
thang chen » chang chen, kang chen, zhang chendi
wang yang » wang liang, wang yanling
wang yong » wang hyoung, wang shiyong
yang binh » yang jin, sang minh, yang jing
yan guan » gan guan, yan yuan, yang guang
yang yue » wang yue, yang yun, yang jui

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 yong ((((yan guan) OR (yang yue))) OR (wang yan)) wang yang binh thang chen ;~.
• Adding a wildcard symbol may retrieve word variants: wang yong ((((yan guan) or (yang yue))) or (wang yan)) wang yang binh thang chen ;*.
