Perhaps you should try some spelling variations:
risk during » risks during, risk using, crisis during
during risk » using risk, during crises, during crisis
done using » move using
wang yuhan » wang luhang, wang yan, wang yidan
risk loans » risky loans, risky loan, risk loss
loans sau » loans law
yet a » et a, yet _, get 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 yuhan)) ((yet a) or (m a)) risk during risk loans sau ;~.
• If you are trying to use Boolean operators, they must be ALL CAPS: ((((done using) OR (line using))) OR (wang yuhan)) ((yet a) OR (m a)) risk during risk loans sau ;*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((((done using) OR (line using))) or (wang yuhan)) ((yet a) or (m a)) risk during risk loans sau ;*".
