Perhaps you should try some spelling variations:
huang ying » huang jing, huang ting, huang yang
boon siong » soon siong, boon chong
john wong » john bonn
john song » john bonn, john ngosong
yang jin » yang jie, yang jun, ying jin
jin li » jin xi, yin li
shin » skin, sein, thin

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: ((huang ying) OR (boon siong)) yang jin li ying ((john wong) OR (john song)) shin ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((huang ying) or (boon siong)) yang jin li ying ((john wong) OR (john song)) shin ;~".
• Adding a wildcard symbol may retrieve word variants: ((huang ying) or (boon siong)) yang jin li ying ((john wong) OR (john song)) shin ;*.
