Perhaps you should try some spelling variations:
boon chong » boon siong, joon chang
chong you » chang you, thing you, chong yah
you check » you hack
tan boon » tan soon, a boon, ar boon
ying jin » yang jin, jing ji, yang jie
chang ha » chang mae
yang yi » yang xi, yang jui

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: tan boon chong you check ((((((yang judy) OR (yang di))) OR (ying jin))) OR (yang yi)) chang ha ;~.
• Adding a wildcard symbol may retrieve word variants: tan boon chong you check ((((((yang judy) or (yang di))) or (ying jin))) or (yang yi)) chang ha ;*.
