Perhaps you should try some spelling variations:
weng john » wong john, wrong john, king john
wong laid » wong lai, kong land
wing yan » wing ian, wing tan, wang yang
tran hua » tan hua, tuan hua, tran duc
ren weng » den weg
wong sam » wong sau, wong lai, kong sar
hua ren » hua chen

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: ((wing yan) OR (wang yan)) tran hua ren weng john ((wong sam) OR (wong laid)) ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((wing yan) OR (wang yan)) tran hua ren weng john ((wong sam) or (wong laid)) ;~".
• Adding a wildcard symbol may retrieve word variants: ((wing yan) OR (wang yan)) tran hua ren weng john ((wong sam) or (wong laid)) ;*.
