Perhaps you should try some spelling variations:
boost during » roosts during, books during, boom during
cost during » crust during, west during, roosts during
work shiu » work six
wong shiu » wong siu, cong shu, song shin
wing ran » wing ian, wing tan, wing sun
ran ying » fan ying, tan ying, jin ying
ying end » big end

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 ran ying end ((cost during) OR (boost during)) risk ((work shiu) OR (wong shiu)) ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "wing ran ying end ((cost during) or (boost during)) risk ((work shiu) OR (wong shiu)) ;~".
• Adding a wildcard symbol may retrieve word variants: wing ran ying end ((cost during) or (boost during)) risk ((work shiu) OR (wong shiu)) ;*.
