Perhaps you should try some spelling variations:
kong saur » kong sar, kong siu, kong your
tan chia » tuan china, than china, can china
yang jin » yang jie, yang jun, ying jin
yong sau » wong sau, kong sar, yong cai
wong sam » wong sau, wong lai, kong sar
wan yan » wang yan, nan yan, wai yan
tan hua » tuan hua, wang hua, tan puay

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: wan yan ((tan hua) OR (tan chia)) rent yang jin ((((yong sau) OR (wong sam))) OR (kong saur)) ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "wan yan ((tan hua) or (tan chia)) rent yang jin ((((yong sau) OR (wong sam))) or (kong saur)) ;~".
• Adding a wildcard symbol may retrieve word variants: wan yan ((tan hua) or (tan chia)) rent yang jin ((((yong sau) OR (wong sam))) or (kong saur)) ;*.
