Perhaps you should try some spelling variations:
during risk » using risk, during crises, during crisis
risk during » risks during, risk using, crisis during
done using » move using
wang yidan » wang yan
risk wong » risk among, risk along, risk work
wong sau » wong sam, wong siu, wong shiu
ka a » kai a, a a, k a

You may be able to get more results by adjusting your search query.

• Performing a fuzzy search may retrieve terms with similar spellings: ((((done using) OR (line using))) or (wang yidan)) ka a risk during risk wong sau ;~.
• If you are trying to use Boolean operators, they must be ALL CAPS: ((((done using) OR (line using))) OR (wang yidan)) ka a risk during risk wong sau ;*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((((done using) OR (line using))) or (wang yidan)) ka a risk during risk wong sau ;*".
