Perhaps you should try some spelling variations:
during risk » using risk, during crises, during crisis
land cost » land costs, land code
risk hong » risk among, risk along, risk how
wing yan » wang yan, wing ian, wing tan
yan ying » fan ying, ran ying, tan ying
end cost » end close, end iot
hong shu » cong shu, tong shui, wong shiu

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

• The words AND, OR and NOT may confuse the search; try adding quotes: "wing yan ying ((end cost) OR (land cost)) during risk hong shu ;~".
• Adding a wildcard symbol may retrieve word variants: wing yan ying ((end cost) OR (land cost)) during risk hong shu ;*.
