Perhaps you should try some spelling variations:
huang ying » huang jing, huang ting, huang yang
hong sheng » dong sheng, hong cheng, fang sheng
kyoung yun » young yun, kyoung yang, hyoung gun
thanh van » thanh dam, thanh vu
habe weil » haben teil, habe wie
habe seit » habe mit, habe sehr, lage seit
binh » bin, minh, dinh

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: binh thanh van ((habe weil) OR (habe seit)) ((huang ying) OR (hong sheng)) kyoung yun ;~.
• Adding a wildcard symbol may retrieve word variants: binh thanh van ((habe weil) or (habe seit)) ((huang ying) or (hong sheng)) kyoung yun ;*.
