Perhaps you should try some spelling variations:
strong typing » strong spin
wang dan » wang yan, wang ban, wang yidan
a strong » _ strong
wong sau » wong sam, wong shiu, wong lai
wong siu » wong shiu, kong siu, wong siew
yang mu » yang du, yang muxi, yang jui
yang xi » yang di, yang yi, 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: wang dan ((yang mu) OR (yang xi)) a strong typing ((wong sau) OR (wong siu)) ;~.
• Adding a wildcard symbol may retrieve word variants: wang dan ((yang mu) or (yang xi)) a strong typing ((wong sau) or (wong siu)) ;*.
