Perhaps you should try some spelling variations:
boon chong » boon siong, joon chang
hong cheng » hong sheng, ong cheng, zong cheng
china der » china des, china den, china under
der lohn » der lohne, die lohn
lohn yue » lohn die, sohn yul
yue kong » yue along, yuen fong, yue wang
kong siu » kong eiu, wong siu, dong sin

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: ((((boon chong) OR (fang sheng))) OR (hong cheng)) can china der lohn yue kong siu ;~.
• Adding a wildcard symbol may retrieve word variants: ((((boon chong) or (fang sheng))) or (hong cheng)) can china der lohn yue kong siu ;*.
