Perhaps you should try some spelling variations:
boon chong » boon siong, joon chang
dong sheng » dung sheng, hong sheng, fang sheng
hong cheng » hong sheng, ong cheng, zong cheng
des lohn » der lohn, den lohn, des wohn
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 (dong sheng))) OR (hong cheng)) can china des lohn yue kong siu ;~.
• Adding a wildcard symbol may retrieve word variants: ((((boon chong) or (dong sheng))) or (hong cheng)) can china des lohn yue kong siu ;*.
