Perhaps you should try some spelling variations:
boon siong » soon siong, boon chong
siong yi » ming yi, siong _, chong yi
pang jun » yang jui
yang jin » yang jie, yang jun, ying jin
yi chen » jui chen
yang yi » yang xi, yang jui
a boon » a book
hai » hadi, haji, hari

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: a boon siong yi chen ((((((pang jun) OR (yang jin))) OR (yang di))) OR (yang yi)) dang hai ;~.
• Adding a wildcard symbol may retrieve word variants: a boon siong yi chen ((((((pang jun) or (yang jin))) or (yang di))) or (yang yi)) dang hai ;*.
