Perhaps you should try some spelling variations:
head credit » bad credit, eat credit, lend credit
during risk » using risk, during crisis, reducing risk
wang liang » wang yang
liang big » liang ying, liang li
big head » big dead, big leap, big red
wong sau » wong sam, wong siu, wong shiu
crises » crisis

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 credit ((during risk) OR (during crises)) wong sau ;~".
• Adding a wildcard symbol may retrieve word variants: wang liang big head credit ((during risk) OR (during crises)) wong sau ;*.
