Perhaps you should try some spelling variations:
during risk » during crises, during crisis, reducing risk
wang liang » wang yang
using risk » using rs, funding risk, rising risks
liang big » liang ying, liang li
head exit » hard exit
big head » big dead, big leap, big red
wong sau » wong sam, wong siu, 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: "wang liang big head exit ((during risk) OR (using risk)) wong sau ;~".
• Adding a wildcard symbol may retrieve word variants: wang liang big head exit ((during risk) OR (using risk)) wong sau ;*.
