Perhaps you should try some spelling variations:
lang yanling » wang yanling, wang yangming, zhang yunling
joan smith » dan smith
smith tom » smith tim, smith from, smith tony
wang lin » wang li, wang qin, yang lin
lee joan » lee jean, lee john, lee alan
yang xi » yang di, yang jui
yang yi » yang di, yang jui
tom hui » tong hui

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: lang yanling ((((yang xi) OR (yang yi))) OR (wang lin)) lee joan smith tom hui ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "lang yanling ((((yang xi) OR (yang yi))) or (wang lin)) lee joan smith tom hui ;~".
• Adding a wildcard symbol may retrieve word variants: lang yanling ((((yang xi) OR (yang yi))) or (wang lin)) lee joan smith tom hui ;*.
