Perhaps you should try some spelling variations:
sharing risk » sharing best, during risk
done using » line using, move using
wang yidan » wang yan
risk wong » risk among, risk along, risk work
done sin » dong sin, done so, done fix
wong sau » wong sam, wong siu, wong shiu
ya a » a a, y a, ye 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 sin) OR (done using))) or (wang yidan)) ya a risk sharing risk wong sau ;~.
• If you are trying to use Boolean operators, they must be ALL CAPS: ((((done sin) OR (done using))) OR (wang yidan)) ya a risk sharing risk wong sau ;.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((((done sin) OR (done using))) or (wang yidan)) ya a risk sharing risk wong sau ;".
• Adding a wildcard symbol may retrieve word variants: ((((done sin) OR (done using))) or (wang yidan)) ya a risk sharing risk wong sau ;*.
