Perhaps you should try some spelling variations:
hyoung yang » kyoung yang
wan hyoung » wang hyoung, man houng, min hyoung
die lasten » die kosten, die ersten
chen zheng » chen zhen, chen aizheng, cheng zhang
zheng rong » chen rong
rong bin » dong bin, song bing, org bin
a las » a los, y las, a law

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: wan hyoung yang ((a las) OR (die lasten)) chen zheng rong bin ;~.
• Adding a wildcard symbol may retrieve word variants: wan hyoung yang ((a las) or (die lasten)) chen zheng rong bin ;*.
