Perhaps you should try some spelling variations:
lang hyoung » wang hyoung, kang young, hwang byoung
tuan china » wuhan china, can china, taiwan china
rents yan » ren yan
wong siu » wong shiu, kong siu, wong sau
non same » non state, non frame, non sales
tan hua » tuan hua, wang hua, tan chia
won sau » wong sau, wong sam
yan ji » yan jiu, ban ji, pan ji

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 ((tan hua) OR (tuan china)) rents yan ji ((((won sau) OR (wong siu))) OR (non same)) ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "lang hyoung ((tan hua) or (tuan china)) rents yan ji ((((won sau) OR (wong siu))) or (non same)) ;~".
• Adding a wildcard symbol may retrieve word variants: lang hyoung ((tan hua) or (tuan china)) rents yan ji ((((won sau) OR (wong siu))) or (non same)) ;*.
