Perhaps you should try some spelling variations:
lang hyoung » wang hyoung, kang young, hwang byoung
hyoung yan » kyoung yang, hyoung gun, kyoung yun
guan rene » juan rene, glas rene
yan guan » gan guan, yan yuan, yang guang
yang jun » yang jui, pang jun, yang jin
wong sam » wong sau, wong lai, von sam
kong siu » kong eiu, wong siu, dong sin
yang yi » yang di, yang xi, 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: lang hyoung yan guan rene ((yang jun) OR (yang yi)) ((((wong sam) OR (kong sar))) OR (kong siu)) ;~.
• Adding a wildcard symbol may retrieve word variants: lang hyoung yan guan rene ((yang jun) or (yang yi)) ((((wong sam) or (kong sar))) or (kong siu)) ;*.
