Perhaps you should try some spelling variations:
boost during » roosts during, boom during, built during
books during » blooms during, banks during, boom during
cost during » crust during, west during, roosts during
work shiu » wong shiu, work six
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) OR (books during)))) risk work shiu ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "wing ran ying end ((cost during) or (((boost during) OR (books during)))) risk work shiu ;~".
• Adding a wildcard symbol may retrieve word variants: wing ran ying end ((cost during) or (((boost during) OR (books during)))) risk work shiu ;*.
