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 zhen » chen zhe
zhen dong » zhen yong, zheng rong, zheng cong
a las » a los, y las, a law
sin » sign, sind, skin

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 zhen dong sin ;~.
• Adding a wildcard symbol may retrieve word variants: wan hyoung yang ((a las) or (die lasten)) chen zhen dong sin ;*.
