wing yanling » wang yanling, wang yangming
patient risk » patients risk, patient task, patient cost
yang jui » yang judy, yang di, yang xi
bank hui » bank api, bank bni, bank has
yang up » tying up, yang jun, hang ups

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

• If you are trying to use Boolean operators, they must be ALL CAPS: wing yanling ((yang up) OR (yang jui)) care ((patients risky) OR (patient risk)) bank hui ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "wing yanling ((yang up) or (yang jui)) care ((patients risky) OR (patient risk)) bank hui ;~".
• Adding a wildcard symbol may retrieve word variants: wing yanling ((yang up) or (yang jui)) care ((patients risky) OR (patient risk)) bank hui ;*.
