Perhaps you should try some spelling variations:
dung sheng » dong sheng, fang sheng, bing sheng
boon siong » soon siong, boon chong
wang yang » wang liang, wang yanling
weng wang » wen wang, weng fang, hong wang
yang jin » yang jie, yang jun, ying jin
jin weng » ein wenig, ein weg, jin ying
yan kong » tan kong, yan cong, nan kong
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 siong) OR (wang yang))) OR (dung sheng)) yang jin weng wang yan kong siu ;~.
• Adding a wildcard symbol may retrieve word variants: ((((boon siong) or (wang yang))) or (dung sheng)) yang jin weng wang yan kong siu ;*.
