Perhaps you should try some spelling variations:
china chang » china zhang, china changqi, china china
chin chang » chain change, china zhang, colin chang
wang nan » wang yan, wang ban, wang dan
tan chia » tuan china, than china, can china
wong sam » wong sau, wong lai, kong sar
tan hua » tuan hua, wang hua, tan puay
long do » long d, long du, longer do

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: wang nan ((tan hua) OR (tan chia)) ((chin chang) OR (china chang)) mae ((wong sam) OR (long do)) ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "wang nan ((tan hua) or (tan chia)) ((chin chang) OR (china chang)) mae ((wong sam) or (long do)) ;~".
• Adding a wildcard symbol may retrieve word variants: wang nan ((tan hua) or (tan chia)) ((chin chang) OR (china chang)) mae ((wong sam) or (long do)) ;*.
